Last change on this file since 2794 was 2794, checked in by llange, 3 years ago

MARS PEM:

  • Add a PEMETAT0 that read "startfi_pem.nc"
  • Add the soil in the model: soil temperature, thermal properties, ice table
  • Add a routine that compute CO2 + H2O adsorption
  • Minor corrections in PEM.F90
