Detailed Description

Version: NCEP-Radiation_aerosols v5.2 Jan 2013

This module has three externally callable subroutines:

aer_init() – initialization; called at the start of run to set up module parameters
aer_update() – updating aerosol data; called within the time loop to check and update data sets
setaer() – mapping aeros profile, compute aeros opticals
