[RegCNET] where is the interface of aerosol and ra diation module?

[Fabien Solmon]

Hi Jianwei

chia and chib are 4d (x,y,x, trac) arrays representing the different
tracer fields that you can choose for as simulation . The SW radiative
properties of the aerosol mixing are calculated in aeroppt.F and they
use some data ( extinction, single scattering albedo and assymetry
parameter) relative to each individual tracer, and defined in
/Main/Common/aeroppt.cb. In aeroppt are calculated the effective
radiative parameters that are used then by the SW code ( radcsw.F and
radclr.F routines ) . The activation of the coupling is piloted by the
variable idirect in the regcm.in : idirect = 2 means that you allows the
radiative perturbation linked to aerosol to feedback in the atmosphere,
idirect 1 , you just calculate a radiative forcing without modifying the
atmospheric fields.

Hope it helps.
