RRTM Radiation

The rrtm_radiation_nml only ever needs to be specified if do_rrtm_radiation = .true. in idealized_moist_phys_nml. If this is the case, then the Rapid Radiative Transfer Model will be the radiation scheme that is used. Isca gives an example script using this radiation scheme.
Some of the most common options for configuring this radiation scheme are described below:

Options

co2ppmv

float
Concentration of \(CO_2\) (ppmv).
Default: 300

Diagnostics

The diagnostics for this module can be specified using the module_name of rrtm_radiation in the diagnostic table file. Some available diagnostics are given below:

olr

Top of atmosphere longwave flux (up is positive).
Dimensions: time, lat, lon
Units: \(Wm^{-2}\)

toa_sw

Top of atmosphere net shortwave flux (down is positive).
Dimensions: time, lat, lon
Units: \(Wm^{-2}\)

flux_lw

Longwave flux at the surface (down only).
Dimensions: time, lat, lon
Units: \(Wm^{-2}\)

flux_sw

Net shortwave flux at the surface (down is positive).
Dimensions: time, lat, lon
Units: \(Wm^{-2}\)
