Mars GCM:
Non-retrocompatible changes of the program util/aeroptical.F90 :

• make the program more generic, as the user now specify in aeroptical.def the aerosols to be computed, as well as the necessary information for each aerosol, that are : aerosol_name,aerosol_mmr(GCM variable name),aerosol_reff(GCM variable name or single value in m),aerosol_rho(value in kg/m3),optpropfile_name
• creation of a separate module aeropt_mod.F90 that can be used by other programs (e.g. for the MCD), with one subroutine reading the ASCII optical properties file, one subroutine interpolating optical properties at a given (wvl,reff) tuple, and one subroutine deallocating the module variables.
• modify the compile program to compile this module aeropt_mod.F90 along with the aeroptical.F90 program. There is no change for the user, which just has to run the command 'compile aeroptical' like before.
• correct the handling of user's wavelength or particle sizes that do not lie within the boundaries of the optical properties file.
