!!!!! ============================================================== !!!!! !!!!! sw-rrtm3 radiation package description !!!!! !!!!! ============================================================== !!!!! ! ! ! this package includes ncep's modifications of the rrtm-sw radiation ! ! code from aer inc. ! ! ! ! the sw-rrtm3 package includes these parts: ! ! ! ! 'radsw_rrtm3_param.f' ! ! 'radsw_rrtm3_datatb.f' ! ! 'radsw_rrtm3_main.f' ! ! ! ! the 'radsw_rrtm3_param.f' contains: ! ! ! ! 'module_radsw_parameters' -- band parameters set up ! ! ! ! the 'radsw_rrtm3_datatb.f' contains: ! ! ! ! 'module_radsw_ref' -- reference temperature and pressure ! ! 'module_radsw_cldprtb' -- cloud property coefficients table ! ! 'module_radsw_sflux' -- spectral distribution of solar flux ! ! 'module_radsw_kgbnn' -- absorption coeffients for 14 ! ! bands, where nn = 16-29 ! ! ! ! the 'radsw_rrtm3_main.f' contains: ! ! ! ! 'module_radsw_main' -- main sw radiation transfer ! ! ! ! in the main module 'module_radsw_main' there are only two ! ! externally callable subroutines: ! ! ! ! 'swrad' -- main rrtm3 sw radiation routine ! ! 'rswinit' -- initialization routine ! ! ! ! all the sw radiation subprograms become contained subprograms ! ! in module 'module_radsw_main' and many of them are not directly ! ! accessable from places outside the module. ! ! ! ! compilation sequence is: ! ! ! ! 'radsw_rrtm3_param.f' ! ! 'radsw_rrtm3_datatb.f' ! !
