Abstract
The influence of carbon dioxide upon the radiative heat budget of the lower few meters of the atmosphere is investigated. For this purpose, Elsasser's (1960) radiative flux tables for the 15 micron carbon dioxide absorption band have been modified as described by Zdunkowski et al. (1966) and extended to very low optical pathlengths. In order to deal with the water vapor overlap effect in the carbon dioxide band, a series of so-called overlap tables have been constructed for different temperatures. These tables have been applied to obtain radiative flux divergence values for selected air masses which represent arctic, temperate, and tropical conditions. Moreover, for comparison purposes, the water vapor flux divergence, representing the total water vapor spectrum, has been determined for some cases, also. The latter task was accomplished by application of the emissivity method, which was also applied, as an independent check, to obtain carbon dioxide flux divergence. It was found in general that the influence of carbon dioxide upon the air layer near the ground should not be neglected. DOI: 10.1111/j.2153-3490.1968.tb00370.x
