4.7.1. Namelist NAM_CH_EMISSIONS

Fortran name Fortran type values default value
CCH_EMIS character(LEN=4) 'NONE','AGGR','SNAP' 'NONE'

  • CCH_EMIS : option for emissions computations:
    • "NONE" : no emission
    • "AGGR" : one aggregated value for each specie and hour
    • "SNAP" : from SNAP data using potential emission & temporal profile

These two options available for the chemical emissions are exclusive. In general, emission inventories are built using the SNAP approach. The data provided can be either under this SNAP form, or under aggregated form, after an additional treatment (data is usually provided from inventory institutes to the user under this form).
