Abstract
This paper presents tables for the computation of the rate of temperature change due to infrared radiation in the free atmosphere. The tables are based on empirical measurements by F. A. Brooks and Robinson of the emissivity of water vapor, and allow the computation of the rate of radiational temperature change at a given level of the atmosphere by a modification of Bruinenberg's equations for the divergence of the net flux. An example is given. Results of the method are compared with those obtained by other methods. A lack of basic evidence on the relationship between emissivity and temperature is noted.
