Little consideration has been given to the radiative budget of the Southern Hemisphere. Yet such information is needed if the general circulation and energy budget of the hemisphere is to be understood. This study presents the results of infrared flux calcula¬tions carried out for the hemisphere for climatological conditions for January and July. The results are given in terms of the resultant heating and cooling rates, the fluxes at the top of the atmosphere, and the net flux divergences for the entire atmospheric column. The 6. 3 and 80 micron water vapor, the 15 micron carbon dioxide, and the 9. 6 micron ozone bands are considered and transmission functions determined from the quasi-random band model, with the exception of the ozone band, for which Walshaw's empirical formula is used. The cal¬culated transmissivities are compared to experimental values and fall within their experimental uncertainties.
