This module sets up surface albedo for SW radiation and surface emissivity for LW radiation. More...

Detailed Description

In the module, the externally callable subroutines are :

sfc_init(): initialization radiation surface data
setalb(): set up four-component surface albedoes
setemis(): set up surface emissivity for lw radiation

SW surface albedo (namelist control parameter - IALB=1)
IALB=0: surface vegetation type based climatology scheme (monthly data in $1^o$ horizontal resolution)
IALB=1: MODIS retrievals based monthly mean climatology

LW surface emissivity (namelist control parameter - IEMS=1)
IEMS=0: black-body emissivity (=1.0)
IEMS=1: surface type based climatology in $1^o$ horizontal resolution
