Summary

A SEPARATION OF VARIABLES SOLUTION HAS BEEN OBTAINED FOR TRANSIENT RADIATIVE COOLING OF AN ABSORBING-SCATTERING PLANE LAYER. THE SOLUTION APPLIES AFTER AN INITIAL TRANSIENT PERIOD REQUIRED FOR ADJUSTMENT OF THE TEMPERATURE AND SCATTERING SOURCE FUNCTION DISTRIBUTIONS. THE LAYER EMITTANCE, EQUAL TO THE INSTANTANEOUS HEAT LOSS DIVIDED BY THE FOURTH POWER OF THE INSTANTANEOUS MEAN TEMPERATURE, BECOMES CONSTANT. THIS EMITTANCE IS A FUNCTION OF ONLY THE OPTICAL THICKNESS OF THE LAYER AND THE SCATTERING ALBEDO ; ITS BEHAVIOUR AS A FUNCTION OF THESE QUANTITIES IS CONSIDERABLY DIFFERENT THAN FOR A LAYER AT CONSTANT TEMPERATURE.
