# ICON templates

There are a few templates for ICON-ART runs built into _auto-icon_. The following table will give you an overview over the different cases:

| Template name | Notes |
| ------------- | ----------- |
| ALLAERO_NORAD **(a)** | Externally mixed natural aerosols without aerosol-radiation interaction. |
| DUST_NOAERODYN | Basic testcase for dust simulation without aerodyn module. |
| DUST_RAD **(a)** | Initialization and processes similar to DWD set-up for operational dust forecast. |
| ERA5_DUST_REINIT | Same as DUST_NOAERODYN with starting from ERA5 data with daily reinitialization of meteorology. |
| ICON_ART_LES | Simple LES dust simulation. |
| IFS_DUST_REMAP | Similar as DUST_NOAERODYN with IFS input remapped with _auto-icon_. |
| LAM_DUST | Limited area run for a dust simulation and with the creation of a grid file. |
| LAM_OEM **(a)** | Online emission module with passive tracers based on TNO emissions. |
| NWP_EXT_DATA | Simple chemistry test run. |
| NWP_GASPHASE **(a, b)** | NWP_GASPHASE | MECCA Chemistry and chemistry initialization with EMAC data. |
| NWP_LIFETIME **(a, b)** | NWP_LIFETIME | Regional tracers, lifetime tracers and Linoz without radiation feedback. |
| REINIT_CHEM | Simple aerosol aeging example and test run with daily reinitialization of chemistry data. |
| VOLAERO_RAD **(a)** | ART tutorial example [Simulating a point source](https://www.icon-art.kit.edu/userguide/index.php?title=Simulating_a_Point_Source); Raikoke simulation published in ACP, Muser er al. 2020, point source is tested too. **(c)** |

**(a)** [ART Standard case](https://www.icon-art.kit.edu/); Retrieval of input data for these cases is build into _auto-icon_ already.

**(b)** These cases use ART code licensed under the GPL license. In order to use these, you have to compile ICON with `--enable-art-gpl` and accept the GPL license.

**(c)** The [tutorial examples](https://www.icon-art.kit.edu/userguide/index.php?title=Tutorial_Examples) are written for the runscript approach but are also running out of the box with _auto-icon_. You can still check out the guides (along with the [guide to transform a runscript to _auto-icon_](/Introductory-guides/Transform-a-runscript-into-an-auto-icon-configuration.md)) to learn more about how ART works, once you are familiar with running _auto-icon_.
