Abstract
The results of special measurements of solar irradiance with high resolution in time domain are compared with results of traditional measurements. Three possible characteristic parameters are studied to describe the dynamic quality of the recorded dataset: standard deviation, frequency density distribution law of increments and the number of fronts of the solar radiation per time unit. Recording traditionally one-minute average values of the solar irradiance, most of the changes cannot be registered in the condition of clouds cumulus humilis.
