Detailed Description

In the module, the externally callable subroutines are :

SW surface albedo (namelist control parameter - IALB=1)
IALB=1: MODIS retrievals based monthly mean climatology
IALB=2: use surface albedo from land model

LW surface emissivity (namelist control parameter - IEMS=1)
IEMS=1: surface type based climatology in \(1^o\) horizontal resolution
IEMS=2: use surface emissivity from land model
