Testsuite: art_local_POLLEN_SPP
===============================

This script prepares an ICON-ART regional NWP experiment for pollen species at 6.5 km resolution (R3B08). The experiment includes prescribed optical properties and aerosol processes for pollen and radioactive aerosols.

Required data for this testcase:
--------------------------------
  - rrtmg_lw.nc 			(longwave radiation properties)
  - ECHAM6_CldOptProps.nc 		(cloud optical properties)
  - PrescribedOpticalProperties_CMD_USE.nc (prescribed aerosol optical properties)
  - iconR3B8_DOM01_lbc.nc 		(lateral boundary conditions)
  - iconR3B8_DOM01.nc 			(main grid for the domain)
  - extpar_iconR3B8_DOM01.nc 		(external parameters for the domain)
  - ART_POC_iconR3B08-grid_0049.grb 	(dust data)
  - ART_POV_iconR3B08-grid_0049.grb 	(volcanic aerosol data)
  - R03B08_DOM01_ilaf20210322000000.grb (initial forcing data)
  - RADRRTM 				(RRTM radiation data)
  - RADSRTM 				(SRTM radiation data)
  - socrates_droplet_scattering_rrtm.nc (cloud droplet scattering)
  - fu_ice_scattering_rrtm.nc 		(ice scattering)
  - mcica_gamma.nc 			(cloud overlap parameters)
  - map_file.ana 			(mapping internal names onto GRIB2 shortnames)
  - map_file.lbc 			(mapping for lateral boundary conditions)
  - map_file.fc 			(mapping for forecast output) 
  - exp.testsuite.pollen_spp_base	(runscript)
  - README.txt                		(this file)

Aerosol configuration:
----------------------
Pollen species (iart_pollen = 1)
Radioactive aerosols (iart_radioact = 1)   
Aerosol washout enabled (iart_aero_washout = 1)
This testcase performs limited area run (l_limited_area = .TRUE.) 

Important Remark
----------------
It is mandatory to set the ECCODES definitions path (including the *.edzw file) before running this experiment. If the path is not available, you can clone the definitions from DWD's ECCODES repository to your local machine.
The following is just an example:

export ECCODES_DEFINITION_PATH=/perm/dwg/grib_api_def/ec-2.28.0/definitions.edzw:/perm/dwg/grib_api_def/ec-2.28.0/definitions

Please ensure that the specified path exists on your system or adjust it accordingly.
