The main results of study of light-climates earth's surface on the Mongolian territory

Abstract

The main light-climatically characteristics, such as duration of natural illumination, light-climatically coefficient, standardize values of the coefficient natural illuminations for buildings (en) situated in some regions of Mongolia and the variability of natural illumination have been determined. The first study of geophysical and astronomical factors effecting the natural illumination regime and interconnection among the atmospheric transparency (P2) with natural illumination of horizontal earth surfaces in Ulaanbaatar was also investigated.
