【 摘 要 】

In this paper, the authors propose a method for determining the main forms of clouds using an analysis of the diurnal variation of direct and diffuse solar radiation. This approach allows operating the process of determining the sky state automatically, which in most cases requires the presence of an observer at the point of measurement. For this purpose, the authors use the direct radiation transmission ratio and diffuse radiation changes with respect to cloudless sky, which have specific values for various forms and types of clouds. The method can be especially effective in cases where measurement of the basic characteristics of radiation is carried out with automatized actinometrical complexes.
