Updates for the aerosol module salsa

  • Reformat the emission data for the pre-processed mode (lod=2) to limit the size of the input file. Now, the emission is given as total number emission per emission category (ncat) and the number size distribution is given in variable emission_number_fracs(ncat,nbins).
  • Implement offline nesting for salsa. Additionally, offline nesting can be turn off specifically for salsa using the switch nesting_offline_salsa.
  • Remove init_aerosol_type and init_gases_type from salsa_parin and define them based on the initializing_actions
  • parameter definition removed from "season" and "season_z01" is added to parin
  • bugfix in application of index_hh after implementing the new palm_date_time_mod
