摘要：

From the total spectral emissivities determined for clear skies in a preceding paper their directional values are obtained. The Bliss formulation still used for this doing is justified. The results point out the inefficiency of a large band around the horizon for cooling purposes. As an application, a natural focusing system to obtain dew is explained. (C) 2003 Elsevier Science Ltd.
