| heal.abstract | The seasonal shortwave radiation budget at the surface of the Southern Hemisphere was estimated, for 10 degrees latitudinal zones, using a radiative transfer model with long-term mean monthly climatological data from the International Satellite Cloud Climatology Project (ISCCP; 1983-90) supplemented by data from the National Centers for Environmental Prediction-National Center for Atmospheric Research (NCEP-NCAR). The computed radiation budget of the Southern Hemisphere is given at both top of the atmosphere (TOA) and at the surface and for each month. The model radiative fluxes at TOA were validated against Earth Radiation Budget Experiment (ERBE) scanner S4 satellite data (1984-89). Initially, large deviations were found for TOA fluxes in the south polar regions, where ISCCP cloud cover data are less certain. The cloud cover was thus modified in the polar regions using ground-based observations and better agreement was obtained. The surface radiative fluxes have been intercompared with other model results and differences are found at high latitudes. The mean annual hemispherical values computed for the outgoing solar flux at TOA, the solar atmospheric absorption, the downwelling, and the net downwelling shortwave radiation at the surface are found to be 103, 81, 174, and 160 W m(-2), respectively. A mean annual hemispherical albedo of 0.296 is computed, which is close to the ERBE value of 0.29. This albedo is found to be similar to that for the Northern Hemisphere, as also suggested by ERBE and Nimbus-7 satellite data. | en |
