# Makefile for running ecRad on clear-sky CKDMIP profiles. The basic
# test uses the single input file INPUT below. You can also run ecRad
# on CKDMIP scenarios (see lower in file). You need the NCO tools
# ncap2, ncrcat and ncpdq.

# --- BASIC TEST ---

# Type "make" to use the default ecckd gas-optics models, or "make
# GASMODEL=rrtmg" for the RRTMG gas-optics model.

# --- CKDMIP SCENARIOS ---

# To run the CKDMIP scenarios you first need to copy the concentration
# files from http://aux.ecmwf.int/ecpds/home/ckdmip/concentrations/,
# or ftp from aux.ecmwf.int (username ckdmip, password any non-empty
# string), which you can do with "make download".  Then do:
#
#    make scenarios
#
# As in the basic test you can add the GASMODEL=rrtmg to use the RRTMG
# gas-optics model instead of ecCKD. To use a different configuration
# of ecCKD than the default, copy config-ecckd.nam to something like
# config-custom.nam, then add the gas_optics_sw_override_file_name and
# gas_optics_lw_override_file_name namelist arguments to specify your
# preferred CKD definition file, and call make with GASMODEL=custom.
