Therefore, it is suitable to study alternating irradiance under such clouds. Measurements were made at the Tallinn University of Technology in the summer season of 2008 and 2009, 59.48° N and 24.65° E at 30m above sea level. The share of such clouds, increments of radiation, methods to select fronts of the irradiance, speed of the cloud (shadows) and their linear dimensions were measured with a sampling interval of 1s. Results of (statistical) analysis are presented in the paper.
