Error in MTso prescribed volcanic aerosols #1494

Description

@fvitt

What is the feature/what would you like to discuss?

Stratospheric aerosol forcings using MAM5 include the following variables:
so4mass_a1, .. a2, .. a3, and now so4mass_a5
diamwet_a1, .. a2, …a3, and now diamwet_a5
SAD_AERO
which are derived from the MTt4 simulation.

These are read in for the stratosphere only, and can be used for chemistry (SAD_AERO) and are used for radiation (mass and diameter). For aerosol optical properties, we need to add VOLC_MMR1,2,3, and VOLC_MMR5.

The namelist setting should be:

rad_climate            = 'A:Q:H2O', 'N:O2:O2',
         'A:CO2:CO2', 'N:ozone:O3',
         'A:N2O:N2O', 'A:CH4:CH4',
         'N:CFC11STAR:CFC11', 'A:CFC12:CFC12',
