Mars GCM:
Changes in aeroptical.F90 :

• add the flag nf90_64bit_offset when creating the output file. Without it, the program couldn't deal with large files (concat) with multiple aerosols
• modify the code structure to make it a bit less memory-intensive
• add topdust in computed aerosol opacities
• add the possibility to compute absorption opacities, instead of extinction : the user must specify 'ext' or 'abs' in aeroptical.def
• update the description of aeroptical in util/README

+ adapt simu_MCS to take into account aeroptical output variables when choosing

the binning reference

+ add outputs for topdust in physiq_mod

AB

+stormdust and topdust present in the input file, at a wavelength given by the user.
 Computation is made from the aerosol mass mixing ratios and effective radius,
 associated with air density (rho) and files containing the aerosol 
 optical properties (generally present in the GCM datadir/ directory).
+The user have to precise the type of opacity : extinction or absorption.
 
 NB : water ice effective radius is known to be a bit inaccurate in the GCM,
