Using MCARaTS **Examples in the package ***Radiation budget applications Input files: conf_hr0213 and conf_hr1100. These are flux and heating rate calculation examples for two wavelengths, 2130 nm and 11000 nm. Spatial distribution of cloud water density for stratocumulus cloud scene was taken from a large eddy simulation. Rayleigh scattering and typical aerosol vertical profile are assumed. Surface reflection is represented by Lambertian model. Simulations are performed for two solar zenith angles (SZAs). Fluxes at top and bottom of the atmosphere and 3-D heating rates are computed. For these cases, important variables in the namelists are listed as follows: Wld_mtarget = 1 ! target mode (1=flux&HR, 2=radiance, 3=volume rendering) Src_nsrc = 2 ! two SZAs Flx_mflx = 1 ! fluxes at TOA and

Controls verboseness of the executable, (de)activating printing messages. This would be useful for testing and debugging. Options are as follows: = 0 : quiet (no message will be printed) 1 : yes 2 : more 3 : most (for debug) ***Wld_jseed integer, save :: Wld_jseed = 0 Seed for random number generator (0 for automatic). Should be positive integer, >= 1 and <= 2**31 - 1 if the user specify the seed. This would be useful in some cases (e.g., when debugging). If Wld_jseed == 0, then the seed is automatically set by the code, using the start date and time. In MPI-parallelized mode, processor element (PE) rank index is also used for the automatic se
