The study presents a probabilistic and statistical assessment of the actinometric characteristics of solar radiation and temperature and humidity parameters of atmospheric air during the hay harvesting period in Kazakhstan. The following characteristics are considered actinometric: The duration of the sunshine period, the total solar radiation flow, and the average intensity of the total solar radiation per unit area of the horizontal surface with clear skies and average cloud cover. From the parameters of atmospheric air, its temperature, humidity, and moisture absorption capacity are calculated. The authors present their average values, standard deviations, confidence intervals for the average value, coefficients of variation, and probability densities of the distribution of these parameters.
