== Setting up ICON-ART ==<br />
<br />
The first thing to do is having a working installation of ICON-art. To check if your icon version has been built correctly, you can check if<br />
your_icon_folder/bin/icon.exe<br />
exists.<br />
<br />
== Setting up Directories ==<br />
<br />
Now a directory structure has to be set up. Usually the following directories are used:<br />
* '''Working Directory''': Here the files that are needed for an individual run are saved. This usually includes the runscript and the relevant .xml files.<br />
* '''Icon Code directory''': This is where the Icon code is stored.<br />
* '''External Data directory''': Here external files which are needed for a run are stored. For example, to parametrize the optical properties of clouds a files like ECHAM6_CldOptProps.nc is used. These files of course can be switched out for others, however in most applications the same ones are used. A list of the used files is given in the runscript, which then creates a link of these files in the output directory.<br />
* '''Output directory''': This is where the new simulation data will be stored. Since most of the time large amounts of data are produced, this is stored in the work or scratch partitions on most HPC systems. The namelists produced by the runfile are also stored here.<br />
<br />
== Setting up the Runscript ==<br />
<br />
The function of the runscript is to set up the directory structure,link the relevant files and create the namelists.<br />
<br />
== Setting up the .xml's ==<br />
Here the .xml<br />
pntSRC.xml<br />
is set up. It contains all the necessary information to describe the emission of the here defined aerosols into the atmosphere.<br />
The following information is contained:<br />
* where is the Pointsource<br />
* when is it emitting<br />
* what substances are emitted<br />
* how much of each substance is emitted<br />
* what size are the emitted substances (median and standard deviation)<br />
<br />
This can be adapted as needed.<br />
<br />
In this example, the Raikoke eruption on 21 of June 2019 is simulated, as can be seen in the following .xml:<br />

== Running the Simulation ==<br />
The setup of the model for the simulation happens with a runscript. It contains all the different control parameters, such as time control of the simulation, what equations are going to be used, whether ART is active, and a lot more.<br />
The runscript itself is just a text file, which is run via bash to start the simulation. Usually a template file is used and adapted to the specific needs of the user running the simulation.<br />
Here we will go through the runscript for our pointsource simulation.<br />
<br />
The first step is to set the relevant directories, so that the XML data we provide as well as the path to the ICON model can be found and accessed easily.<br />
In this simulation, external data such as a grid containing external parameter data is required. The directory containing the data is set as DATADIR.<br />
The output directory is where the model will write the output into, as well as linking a lot of relevant files used in the simulation.<br />
<br />
<syntaxhighlight line lang=bash class="mw-collapsible-content"><br />
# working directory<br />
export XMLDIR=/your/path/to/Training2023/Volcano<br />
<br />
# datadir2 --> do not change<br />
export DATADIR=/your/path/to/DATA_Volcano<br />
<br />
# output directory<br />
export OUTDIR=/your/path/to/Volcano_externally<br />
<br />
# Code directory<br />
export ICONDIR=/your/path/to/icon-kit<br />
export ARTDIR=${ICONDIR}/externals/art<br />
<br />
</syntaxhighlight><br />
<br />
In the next step, the previously defined output directory is created, if not already there, and the icon executable is linked into it for easier access and overview.<br />
<br />
<syntaxhighlight line lang=bash class="mw-collapsible-content"><br />
if [ ! -d $OUTDIR ]; then<br />
mkdir -p $OUTDIR<br />
fi<br />
<br />
cd $OUTDIR<br />
<br />
# copy icon binary to OUTDIR<br />
cp ${ICONDIR}/bin/icon icon.exe<br />
</syntaxhighlight><br />
<br />
<br />
Now, the external parameters and chemistry files are linked into the output directory, so that after running the simulation it can be identified which have been used.<br />
<syntaxhighlight line lang=bash class="mw-collapsible-content"><br />
ln -sf ${DATADIR}/icon_grid_0024_R02B06_G.nc ${OUTDIR}/iconR2B06-DOM01.nc<br />

<br />
In the next step, we create the namelists. They are written into the output directory.<br />
First the master namelist is created, which most importantly contains the start and stop date, as well as the possibility to restart a run.<br />
The next namelist created is called "NAMELIST_Raikoke-June-2019". Here a lot of the model setup is taking place. It is subdivided into different smaller namelist parts, which all do their part to set up a different part of the model.<br />
Some important namelists for this simulation are:<br />
* grid_nml (line 35): Here the grid on which the simulation is taking place is given<br />
* run_nml (line 49): Contains the switch to turn on ICON-ART, as well as set model height levels and timestep length.<br />
* output_nml (line 225): Defines which variables at which intervals are written in the output directory<br />
* art_nml (line 238): Contains the switches relevant for ICON-ART, see [[Namelist]] for more details. Most importantly, the xml file for the point source emission is linked here<br />

With the namelists set, we can now prepare the simulation for running. Since a lot of setup is required for running, this is also prepared within the runscript and then later executed. The following part is highly dependant on the HPC system configuration. The following setup works on the DKRZ Levante HPC system:<br />

ENDFILE<br />
</syntaxhighlight><br />
This concludes the runfile.<br />
The Job_ICON-file that has been produced in the last step can then be executed. For that, firstly the runfile hast to be run using bash:<br />
<syntaxhighlight lang=bash class="mw-collapsible-content"><br />
$ chmod +x myrunfile<br />
$ ./myrunfile<br />
</syntaxhighlight><br />
This will then create all the Namelists and the runscript job_ICON. To then submit the icon run, go to the output directory, make the runscript executable, and run it:<br />
<syntaxhighlight lang=bash class="mw-collapsible-content"><br />
$ cd /path/to/your/output<br />
$ chmod +x job_ICON<br />
$ sbatch job_ICON<br />
</syntaxhighlight><br />
with that, the Job should be submitted. The submission status can be seen with<br />
<syntaxhighlight lang=bash class="mw-collapsible-content"><br />
$ squeue --user your_username<br />
</syntaxhighlight><br />
<br />
If everything went well, in the Output directory there will be output files generated with names like Raikoke-June-2019-forecast_mode-remap_DOM01_ML_0001.nc<br />
== Inspecting the Output ==<br />
In this example, the output is created in the form of several NetCDF4 (.nc) files. To avoid having one giant file, it is subdivided into several files containing a fixed amount of timesteps. The quickest way to inspect a NetCDF file is with [https://code.mpimet.mpg.de/projects/cdo CDO]:<br />
<syntaxhighlight lang=bash class="mw-collapsible-content"><br />
$ cdo sinfo Raikoke-June-2019-forecast_mode-remap_DOM01_ML_0001.nc<br />
</syntaxhighlight><br />
This way it is possible to obtain information about the variables, grid parameters and timesteps of the simulation. To actually see the values of a specific variable, tools like ncdump can be used, however in many cases this is not practical, since the amount of single values is way too large to look at individual data points.<br />
<br />
== Making a Plot of the Simulation Data ==<br />
In order to gain insight into the simulation, as well as an overview, the most common way is to create some plots of different variables of interest. In our case, we want to know what happens to the ash emitted from the Raikoke eruption.<br />
A quick and easy way to create plots is using python and a reference script to produce a plot similar to the Pointsource animation is given here:<br />
<syntaxhighlight line lang=python class="mw-collapsible-content"><br />
# first we import the following packages:<br />
import numpy as np # general utility for trigonomic functions and arrays<br />
import matplotlib.pyplot as plt # Library to produce Plots<br />
import xarray as xr # reading in of netCDF data, optimized for large datasets<br />
import cartopy.crs as ccrs # plotting things on a map<br />
<br />
#Next step: read in the Netcdf Files<br />
<br />
#datadir_externally = 'path/to/your/output/Training2023/Volcano_externally/'<br />
files_externally = glob(datadir_externally+'Raikoke-June-2019-forecast_mode-remap_DOM01_ML*')<br />
files_externally.sort()<br />
<br />
#Next step: Calculate relevant data to be displayed<br />
# get model level height<br />
def get_dz(ds):<br />
dz = -1 * ds.z_ifc.diff('height_2')<br />
dz = dz.rename({'height_2':'height'})<br />
dz = dz.assign_coords(height=(dz.height - 1))<br />
return dz<br />
<br />
# Calculate column integrated tracer mass (tracer load)<br />
def tracer_load(tr,rho,dz):<br />
m_tr = tr * rho * dz<br />
m_tr = m_tr.sum('height')<br />
m_tr = m_tr.squeeze()<br />
return m_tr<br />
<br />
#<br />
MM_SO2 = 64/28.96 # molar weight of SO2 / dry air<br />
<br />
<br />
# set the timestep you want to plot<br />
# in this simulation there are 144 timesteps and 144 files each containing one timestep<br />
# To produce a plot for each timestep, you can also loop the rest of this file over i<br />
i = 1<br />
<br />
#load the NetCDF file containing the timestep<br />
ds = xr.open_dataset(files_externally[i],autoclose=True)<br />
<br />
#calculate Heightlevels<br />
dz = get_dz(ds)<br />
<br />
# Read in SO2 Column<br />
SO2 = tracer_load(ds.TRSO2_chemtr.values*MM_SO2,ds.rho,dz)<br />
<br />
# set colorbar levels<br />
color_so2 = np.linspace(1e-5, 0.02, 11,endpoint=True)<br />
<br />
<br />
# Plot SO2 column<br />
# set the size of the figure and the background color to white<br />
fig = plt.figure(figsize=(8,6),facecolor='w')<br />
<br />
# Set the axes using the specified map projection<br />
ax=plt.axes(projection=ccrs.NearsidePerspective(central_longitude=180, central_latitude=49.29,satellite_height=35785831/5, globe=None))<br />
ax.stock_img() #add a stock image as background<br />
ax.coastlines() # add coastlines<br />
ax.set_title(str(ds.time.values)[2:12]+" "+str(ds.time.values)[13:18]) #set title to the current time displayed<br />
ax.gridlines(draw_labels=False, dms=False, x_inline=True, y_inline=True) #add lat lon gridlines<br />
<br />
# Make a filled contour plot<br />
plot1=ax.contourf(ds.lon, ds.lat, SO2, levels=color_so2, cmap='plasma',<br />
transform = ccrs.PlateCarree())<br />
kwargs = {'format': '%.3f'}<br />
cbar = plt.colorbar(plot1,location='right',ticks=color_so2,**kwargs)<br />
cbar.set_label('SO2 Column Mass (kg m-2)')<br />
<br />
#save the plot at a path of your choice<br />
<br />
#plt.savefig("path/to/your/Plots/folder/SO2_{:03d}.png".format(i))<br />

== Recommended ICON Namelist Settings ==<br />
<br />
It is necessary for the user to choose the ICON settings carefully. Part of the values listed in are recommended to obtain a stable ICON-ART simulation with scientifically reasonable results. Another part is necessary to enable ART features like aerosol-cloud-interactions.<br />

== ART Namelists ==<br />
<br />
ICON-ART has an own namelist to modify the setup of ART simulations at runtime. The main switch for ART, lart, is located inside run_nml. The namelist for the other ART switches is called art_nml.<br />
<br />
A naming convention is used in order to show the type of data. An INTEGER namelist parameter starts with iart_, a REAL namelist parameter starts with rart_, a LOGICAL namelist parameter starts with lart_, and a CHARACTER namelist parameter starts with cart_.<br />
<br />
The ICON-ART namelist is located in the module src/namelists/mo_art_nml.f90. General namelist parameters are listed and explained within . Namelist parameters for ART input are listed within . Namelist parameters related to atmospheric chemistry are listed within . Namelist parameters related to aerosol physics are listed within . Namelist parameters related to feedback processes between aerosols and meteorological variables are listed in . Finally, namelist parameters related to physics parameterizations in ICON are listed in.<br />

<div><h1 id="chap:outputs">Output</h1> <p><em>Last Update: 2014/06/24 Daniel Rieger</em></p> <p>In principle, output of ICON-ART variables works the same way as for ICON variables. As described in <span class="citation" data-cites="icon:user_guide"></span>, the following five quantities of the output have to be specified:</p> <ul> <li><p>The time interval between two model outputs.</p></li> <li><p>The name of the output file.</p></li> <li><p>The name of the variable(s) and/or variable group(s).</p></li> <li><p>The type of vertical output grid.</p></li> <li><p>The type of horizontal output grid.</p></li> </ul> <p>It is recommended to use NETCDF output on an interpolated grid. A corresponding output namelist for sea salt on model levels can be seen here:</p> <pre data-frame="single"><code>NAMELIST EXAMPLE &amp;output_nml filetype = 4 ! output format: 2=GRIB2, 4=NETCDFv2 dom = 1 ! write output for domain 1 output_start = &quot;JJJJ-MM-DDTHH:MM:SSZ&quot; !put date in output_end = &quot;JJJJ-MM-DDTHH:MM:SSZ&quot; !put date in output_interval = &quot;PT1H&quot; ! \href{ISO8601}{https://en.wikipedia.org/wiki/ISO_8601} steps_per_file = 1 ! max. num. of time steps within one file mode = 1 ! 1: forecast mode (relative t-axis) include_last = .TRUE. ! include the last time step output_filename = &#39;&lt;INSERTFILENAME&gt;&#39; ! file name base ml_varlist = &#39;seasa&#39;,&#39;seasb&#39;,&#39;seasc&#39;, &#39;seasa0&#39;,&#39;seasb0&#39;,&#39;seasc0&#39; remap = 1 ! output is transferred to lat long grid reg_lon_def = -180.,0.5,179.5 !start, incr., end, in deg. reg_lat_def = 90.,-0.5, -90. !start, incr., end, in deg.</code></pre> <p>There is an option to obtain all sea salt variables without having to specifying all of them. Therefore, you may use the group ART_AERO_SEAS.</p> <p>This changes the namelist variable ml_varlist from the example above to the following:</p> <pre data-frame="single"><code>ml_varlist = &#39;group:ART_AERO_SEAS&#39;</code></pre> <p>The output variables that are associated to this group will be written.

For this purpose CDO version 1.6.2rc3 is required currently (see <a href="https://code.zmaw.de/projects/cdo">https://code.zmaw.de/projects/cdo</a>).</p> <p>For more information about the usage please refer to the README-file within the SAMOA package. You can get a copy of the SAMOA script by writing an e-mail to the contact person of the ART code (see <a href="http://icon-art.imk-tro.kit.edu">http://icon-art.imk-tro.kit.edu</a>). SAMOA is licensed under the GNU GENERAL PUBLIC LICENSE Version 3.</p> <p>As SAMOA is primarily developed for the usage with COSMO-ART and COSMO-CLM, you have to do a minor change before using it. The latest version of SAMOA has a list for the usage of SAMOA with ICON-ART output included but not loaded automatically. This list is called samoa_list_icon-art. You have to replace the default (COSMO) list that is used by SAMOA by editing samoa.sh:</p> <p>Search for the following lines:</p> <pre><code># Path to the list with variables (is overwritten when -l specified) # Assumed to be on the same path as script path_list=$SCRIPTPATH/list </code></pre> <p>Change the name of the list to:</p> <pre><code>path_list=$SCRIPTPATH/samoa_list_icon-art </code></pre> <p>Now you may use SAMOA with the ICON-ART output file out.nc with the following command:</p> <pre><code>./samoa.sh out.nc</code></pre> <p>For all options see:</p> <pre><code>./samoa.sh --help</code></pre> <h2 id="visualisation">Visualisation</h2> <p>The horizontal grid structure of the output is essential for the visualization. In general, there are two possibilities. The output may exist on the ICON grid and it may exist on an interpolated longitude/latitude grid. This can be chosen by adaptions of the output namelist (see <a href="#chap:output" data-reference-type="autoref" data-reference="chap:output">[chap:output]</a>). Although it comes along with a loss in information, it is recommended to use interpolated output. By this, the visualization is much easier to handle.</p> <p>In the following sections, three tools are introduced which can be used to visualize ICON output. Note, that <strong>only NETCDF</strong> is supported by ICON-ART so far. With the tool Ncview (see <a href="#sec:ncview" data-reference-type="autoref" data-reference="sec:ncview">[sec:ncview]</a>) it is very easy to have a quick look into the interpolated model output. NCL (see <a href="#sec:NCL" data-reference-type="autoref" data-reference="sec:NCL">[sec:NCL]</a>) is a very comprehensive tool for all kind of data formats and visualization. With ParaView (see <a href="#sec:ParaView" data-reference-type="autoref" data-reference="sec:ParaView">[sec:ParaView]</a>), a nice-looking three-dimensional visualization can be created.</p> <h3 id="sec:ncview">Ncview</h3> <p>"Ncview is a visual browser for netCDF format files. Typically you would use ncview to get a quick and easy, push-button look at your netCDF files. You can view simple movies of the data, view along various dimensions, take a look at the actual data values, change color maps, invert the data, etc." (<a href="http://meteora.ucsd.edu/~pierce/ncview_home_page.html">http://meteora.ucsd.edu/~pierce/ncview_home_page.html</a>)</p> <h3 id="sec:NCL">NCL</h3> <p>"NCL is an interpreted language designed specifically for scientific data analysis and visualization.

<hr />
<div><h1 id="chap:input">Input</h1> <h2 id="requirements-for-a-simulation">Requirements for a Simulation</h2> <p>To run a simulation with ICON-ART installed the first thing to prepare is the runfile. It is usually best to start with an existing and working runfile and adapt parts as needed. The runfile contains the majority of parameters to run a simulation, like the length, timesteps and grids used, as well as a variety of options for methods and parametrisations used in the model. The runfile contents are then split up in several namelists that the model reads at the beginning of a simulation. An overview of the Namelist Parameters can be found in chapter <a href="#chap:namelist" data-reference-type="ref" data-reference="chap:namelist">[chap:namelist]</a>.</p> <p>To enable ART in an ICON simulation, the switch <code>lart = .TRUE.</code> has to be set in the section <code>&amp;run_nml</code>. This is the global on/off switch for ICON-ART. This is how this could look like in the context of a runfile:</p> <pre data-frame="single" data-commandchars="\\\{\}"><code>! run_nml: general switches ---------- &amp;run_nml ltestcase = .FALSE. num_lev = 50 ltransport = .TRUE. ............. \textcolor{red}{lart = .TRUE.}</code></pre> <p>Generally the first letters of a namelist switch refer to its type, the "l" in "lart" stands for logical, meaning it has to be either True or False. Table <a href="#tab:vartypes" data-reference-type="ref" data-reference="tab:vartypes">1.1</a> lists some examples.</p> <div id="tab:vartypes"> <table> <caption>Some namelist switches and their data types.</caption> <thead> <tr class="header"> <th style="text-align: left;">namelist switch</th> <th style="text-align: left;">type</th> </tr> </thead> <tbody> <tr class="odd"> <td style="text-align: left;"><code>lart</code></td> <td style="text-align: left;">logical</td> </tr> <tr class="even"> <td style="text-align: left;"><code>cart_aerosol_xml</code></td> <td style="text-align: left;">character</td> </tr> <tr class="odd"> <td style="text-align: left;"><code>iart_init_aero </code></td> <td style="text-align: left;">integer</td> </tr> </tbody> </table> </div> <p>The namelist <code>&amp;art_nml</code> is used for general options of the ART simulation. To run a certain kind of simulation the according switch has to be set to <code>.TRUE.</code>. For Example to include a point source the switch <code>cart_aerosol_xml</code> has to be set to <code>.TRUE.</code>. This enables the inclusion of a .xml file containing additional information like location and strength of the point source. Table <a href="#tab:art_nml-params" data-reference-type="ref" data-reference="tab:art_nml-params">1.6</a> contains the most important <code>&amp;art_nml</code> namelist parameters and additional namelist parameters required if they are set to <code>.TRUE.</code>.</p> <div id="tab:art_nml-params"> <table> <caption>General art_nml namelist switches and respective parameters.</caption> <thead> <tr class="header"> <th style="text-align: left;">Namelist parameter</th> <th style="text-align: left;">Default</th> <th style="text-align: left;">Description</th> <th style="text-align: left;">If .TRUE. then needs</th> </tr> </thead> <tbody> <tr class="odd"> <td style="text-align: left;"><code>lart_chem</code></td> <td style="text-align: left;">.FALSE.</td> <td style="text-align: left;">Enables chemistry.</td> <td style="text-align: left;"><code>lart_chemtracer = .TRUE.</code></td> </tr> <tr class="even"> <td style="text-align: left;"></td> <td style="text-align: left;"></td> <td style="text-align: left;"></td> <td style="text-align: left;">OR <code>lart_mecca = .TRUE.</code></td> </tr> <tr class="odd"> <td style="text-align: left;"><code>lart_chemtracer</code></td> <td style="text-align: left;">.FALSE.</td> <td style="text-align: left;">Switch for simple OH chemistry</td> <td style="text-align: left;"><code>cart_chemtracer_xml</code></td> </tr> <tr class="even"> <td style="text-align: left;"><code>lart_mecca</code></td> <td style="text-align: left;">.FALSE.</td> <td style="text-align: left;">Switch for kpp chemistry</td> <td style="text-align: left;"><code>cart_mecca_xml</code></td> </tr> <tr class="odd"> <td style="text-align: left;"><code>lart_pntSrc</code></td> <td style="text-align: left;">.FALSE.</td> <td style="text-align: left;">Enables addition of point sources</td> <td style="text-align: left;"><code>cart_pntSrc_xml</code></td> </tr> <tr class="even"> <td style="text-align: left;"><code>lart_aerosol</code></td> <td style="text-align: left;">.FALSE.</td> <td style="text-align: left;">Main switch for the treatment of</td> <td style="text-align: left;"><code>cart_aerosol_xml</code></td> </tr> <tr class="odd"> <td style="text-align: left;"></td> <td style="text-align: left;"></td> <td style="text-align: left;">atmospheric aerosol.</td> <td style="text-align: left;">and <code>cart_modes_xml</code></td> </tr> <tr class="even"> <td style="text-align: left;"><code>lart_diag_out</code></td> <td style="text-align: left;">.FALSE.</td> <td style="text-align: left;">Enables diagnostic output fields</td> <td style="text-align: left;"><code>cart_diagnostics_xml</code></td> </tr> </tbody> </table> </div> <p>The reason for the use of those additional .xml files is that the ART variables (sea salt, mineral dust etc.) they contain might be different for every run which differs from the Icon Variables (Temperature, Pressure, etc.) which usually donÔÇÖt change between runs. .xml files are readable for both humans and machines, which makes them easy to tweak and integrate. An Example for the contents of an .xml file adding ash particles can be seen below.</p> <pre data-frame="single" data-commandchars="\\\{\}"><code>&lt;modes&gt; &lt;aerosol id=&quot;asha&quot;&gt; &lt;kind type=&quot;char&quot;&gt;2mom&lt;/kind&gt; &lt;d_gn type=&quot;real&quot;&gt;1.190E-6&lt;/d_gn&gt; &lt;sigma_g type=&quot;real&quot;&gt;1.410E+0&lt;/sigma_g&gt; &lt;rho type=&quot;real&quot;&gt;2.600E+3&lt;/rho&gt; &lt;/aerosol&gt; &lt;/modes&gt;</code></pre> <p>Further .xml examples can be fount in <code>/your_ART_Directory/runctrl_examples/xml_ctrl. </code></p> <h4 id="additional-input-data">Additional Input Data</h4> <p>Depending on the type of simulation there might be additional input files required.

<h1 id="chap:gettingstarted">Getting Started</h1> <h2 id="overview">Overview</h2> <p>ICON-ART is a state-of-the-science seamless model system for the whole atmosphere (physics and composition) that comprises the key components of the next generation Earth system model in Germany. ICON is a global weather and climate model solves the full three-dimensional non-hydrostatic and compressible Navier-Stokes equations on an icosahedral grid and allows seamless predictions from local to global scales. Aerosol and Reactive Trace gases (ART), as a submodule of ICON, supplements the model by including emissions, transport, gas phase chemistry, and aerosol dynamics in the troposphere and stratosphere (as seen in figure <a href="#ART-capabilities" data-reference-type="ref" data-reference="ART-capabilities">1.1</a>).</p> <figure> <img src="figures/ART-capabilities.png" id="ART-capabilities" alt="Capabilities of ICON-ART and how they relate to each other." /> <figcaption aria-hidden="true">Capabilities of ICON-ART and how they relate to each other.</figcaption> </figure> <p>Being a seamless model makes it possible to use ART to simulate processes overarching multiple scales, like the emission of greenhouse gases, aerosol-cloud interactions and atmospheric chemistry as indicated in figure <a href="#ART-seamless" data-reference-type="ref" data-reference="ART-seamless">1.2</a>. It also enables its use as a prediction tool for the production of renewable energy.</p> <figure> <img src="figures/ART-seamless.png" id="ART-seamless" alt="ICON-ARTÔÇÖs cpabilities for seamless prediction." /> <figcaption aria-hidden="true">ICON-ARTÔÇÖs cpabilities for seamless prediction.</figcaption> </figure> <h2 id="sec:general_remarks">Getting the source code</h2> <p><em>Last Update: 2014/06/18 Daniel Rieger</em></p> <p>A user who wants to work with ICON-ART has to sign the ICON license agreement with the German Weatherservice (DWD) and Max-Planck-Institute for Meteorology (MPI-M) first. Further information can be found on the following website:</p> <p><a href="https://code.mpimet.mpg.de/projects/iconpublic">https://code.mpimet.mpg.de/projects/iconpublic</a></p> <p>In order to obtain the ART code, the institution that wants to use ICON-ART has to sign an additional license agreement with Karlsruhe Institute of Technology (KIT). Further information can be found on the following website:</p> <p><a href="http://icon-art.imk-tro.kit.edu">http://icon-art.imk-tro.kit.edu</a></p> <p>After you have signed the license agreement, you will be provided with a compressed file with the recent source code of ART which is called ART-v&lt;X&gt;.&lt;YY&gt;.tar.gz. &lt;X&gt; and &lt;YY&gt; indicate the version numbers.</p> <h2 id="sec:installation">Installation</h2> <p><em>Last Update: 2016/05/25 Jonas Straub</em></p> <p>In this section, a brief description of how to compile ICON-ART is given.

First, the ART-v&lt;X&gt;.&lt;YY&gt;.tar.gz file has to uncompressed. You will obtain a directory, which should be copied inside the ICON source directory $ICON-DIR/src/. In the following, we refer to this directory<br /> $ICON-DIR/src/ART-v&lt;X&gt;.&lt;YY&gt; as $ARTDIR.</p> <p>If you have compiled ICON as recommended first without ART, you have to do clean up first:</p> <div class="small"> <pre><code> make distclean</code></pre> </div> <p>In order to compile ICON-ART, an additional flag has to be set at the configuration command:</p> <div class="small"> <pre><code> ./configure --with-fortran=cray --with-art</code></pre> </div> <p>By setting ÔÇôwith-art a compiler flag -D__ICON_ART is set. This flag tells the preprocessor to compile the code inside the ART interfaces and hence connect the ICON code with the ART code.

<h1 id="chap:gettingstarted">Getting Started</h1> <h2 id="overview">Overview</h2> <p>ICON-ART is a state-of-the-science seamless model system for the whole atmosphere (physics and composition) that comprises the key components of the next generation Earth system model in Germany. ICON is a global weather and climate model solves the full three-dimensional non-hydrostatic and compressible Navier-Stokes equations on an icosahedral grid and allows seamless predictions from local to global scales. Aerosol and Reactive Trace gases (ART), as a submodule of ICON, supplements the model by including emissions, transport, gas phase chemistry, and aerosol dynamics in the troposphere and stratosphere (as seen in figure <a href="#ART-capabilities" data-reference-type="ref" data-reference="ART-capabilities">1.1</a>).</p> <figure> <img src="figures/ART-capabilities.png" id="ART-capabilities" alt="Capabilities of ICON-ART and how they relate to each other." /> <figcaption aria-hidden="true">Capabilities of ICON-ART and how they relate to each other.</figcaption> </figure> <p>Being a seamless model makes it possible to use ART to simulate processes overarching multiple scales, like the emission of greenhouse gases, aerosol-cloud interactions and atmospheric chemistry as indicated in figure <a href="#ART-seamless" data-reference-type="ref" data-reference="ART-seamless">1.2</a>. It also enables its use as a prediction tool for the production of renewable energy.</p> <figure> <img src="figures/ART-seamless.png" id="ART-seamless" alt="ICON-ARTÔÇÖs cpabilities for seamless prediction." /> <figcaption aria-hidden="true">ICON-ARTÔÇÖs cpabilities for seamless prediction.</figcaption> </figure> <h2 id="sec:general_remarks">Getting the source code</h2> <p><em>Last Update: 2014/06/18 Daniel Rieger</em></p> <p>A user who wants to work with ICON-ART has to sign the ICON license agreement with the German Weatherservice (DWD) and Max-Planck-Institute for Meteorology (MPI-M) first. Further information can be found on the following website:</p> <p><a href="https://code.mpimet.mpg.de/projects/iconpublic">https://code.mpimet.mpg.de/projects/iconpublic</a></p> <p>In order to obtain the ART code, the institution that wants to use ICON-ART has to sign an additional license agreement with Karlsruhe Institute of Technology (KIT). Further information can be found on the following website:</p> <p><a href="http://icon-art.imk-tro.kit.edu">http://icon-art.imk-tro.kit.edu</a></p> <p>After you have signed the license agreement, you will be provided with a compressed file with the recent source code of ART which is called ART-v&lt;X&gt;.&lt;YY&gt;.tar.gz. &lt;X&gt; and &lt;YY&gt; indicate the version numbers.</p> <h2 id="sec:installation">Installation</h2> <p><em>Last Update: 2016/05/25 Jonas Straub</em></p> <p>In this section, a brief description of how to compile ICON-ART is given. The user has to do the same steps as compiling ICON with a few additions. The reader is referred to <span class="citation" data-cites="icon:user_guide"></span> in order to compile ICON successfully. First, the ART-v&lt;X&gt;.&lt;YY&gt;.tar.gz file has to uncompressed. You will obtain a directory, which should be copied inside the ICON source directory $ICON-DIR/src/. In the following, we refer to this directory<br /> $ICON-DIR/src/ART-v&lt;X&gt;.&lt;YY&gt; as $ARTDIR.</p> <p>If you have compiled ICON as recommended first without ART, you have to do clean up first:</p> <div class="small"> <pre><code> make distclean</code></pre> </div> <p>In order to compile ICON-ART, an additional flag has to be set at the configuration command:</p> <div class="small"> <pre><code> ./configure --with-fortran=cray --with-art</code></pre> </div> <p>By setting ÔÇôwith-art a compiler flag -D__ICON_ART is set. This flag tells the preprocessor to compile the code inside the ART interfaces and hence connect the ICON code with the ART code. As soon as the configuration is finished, you can start to compile the ICON-ART code:</p> <div class="small"> <pre><code> ./build_command</code></pre> </div> <h2 id="running-a-job">Running a Job</h2> <p><em>Last Update: 2016/05/25 Jonas Straub</em></p> <p>For a user who succeeded in running the ICON model, there are only a few steps to run the ART extension along with the ICON model. A description how to run the ICON model can be found in <span class="citation" data-cites="icon:user_guide"></span>.</p> <p>In order to run ICON-ART, one has to do the following steps:</p> <ul> <li><p>Configure the code with the additional flag ÔÇôenable-art as described in <a href="#sec:installation" data-reference-type="autoref" data-reference="sec:installation">[sec:installation]</a>.</p></li> <li><p>Prepare the input data</p></li> <li><p>Inside the runscript in the namelist run_nml, set the main switch for ICON-ART to true: lart = .true.</p></li> <li><p>Add a namelist art_nml and choose the namelist parameters for the ART setup as described in <a href="#chap:namelist" data-reference-type="autoref" data-reference="chap:namelist">[chap:namelist]</a>.</p></li> <li><p>Adapt the XML files for tracers, emi. The number of tracers related to a specific setup is equal to the number of possible prognostic output fields as described in <a href="#chap:output" data-reference-type="autoref" data-reference="chap:output">[chap:output]</a>.</p></li> <li><p>Add an output namelist as described in <a href="#chap:output" data-reference-type="autoref" data-reference="chap:output">[chap:output]</a> for the species you are interested in.</p></li> <li><p>Submit the job analogous to an ICON job.</p></li> </ul></div>Admin 2https://www.icon-art.kit.edu/userguide/index.php?title=Main_Page&diff=9Main Page2022-09-01T08:48:08Z<p>Admin 2: </p>
