Effect of the orientation degree of crystalline ice particles in cirrus on the total flow of solar radiation in the photosynthetically active range

摘要

Results of complex experiments, in which flows of solar radiation are measured near the Earth's surface in the presence of cirrus cloudiness and the orientation degree of ice crystals in cirrus is estimated using a polarization lidar, are discussed. Significant effect of the orientation degree of cirrus particles on the transmission of solar radiation is found in a number of experiments.
