Functions/Subroutines | |
| subroutine, public | module_radlw_main::rlwinit |
| This subroutine performs calculations necessary for the initialization of the longwave model. lookup tables are computed for use in the lw radiative transfer, and input absorption coefficient data for each spectral band are reduced from 256 g-point intervals to 140. More... | |
| subroutine | module_radlw_main::mcica_subcol |
| This suroutine computes sub-colum cloud profile flag array. More... | |
| subroutine | module_radlw_main::setcoef |
| This subroutine computes various coefficients needed in radiative transfer calculations. More... | |
| subroutine | module_radlw_main::rtrn |
| This subroutine computes the upward/downward radiative fluxes, and heating rates for both clear or cloudy atmosphere. Clouds assumed as randomly overlaping in a vertical column. More... | |
| subroutine | module_radlw_main::taumol |
| This subroutine contains optical depths developed for the rapid radiative transfer model. More... | |
