Scripts to create emissions files in the right format for PREP PGD

PREP_PGD step

The following scripts are designed to convert the original emission files taken from the GEIA/ECCAD international program (http://eccad.sedoo.fr) to the latitude-longitude-value ascii format needed by the PREP_PGD .

Emissions files are downloaded from the ECCAD web site in the netcdf format.

The script emiss_conv_nc_to_asc.ncl converts netcdf format to lat-lon-val with final emissions in molec/cm2/s.

The script needs to be adapted to the user requirements:

MESONH step

When running the model, the routine build_emisstabn.F90 in SURFEX will automatically make the conversion of the above mentioned units to molec/m2/s according to the keyword provided in the chemistry file under the EMISUNIT keyword: MOL (if emissions are provided in microMol/m2/day), MIX (if emissions are provided in ppp m/s), CON (emissions are provided in molec/cm2/s).

Examples:

EMISUNIT
emission fluxes in microMole/m2/day
MOL

EMISUNIT
emission fluxes in ppp m/s 
MIX

EMISUNIT
emission fluxes in molec/cm2/s
CON
