Abstract
Angstrom formula parameters for spring conditions of an arid zone of Kazakhstan are received. Values of the Angstrom indicator changes from 0.6 to 3.6, and its average equals 2. Hourly average values of the Angstrom indicator are in range of 1.7÷2.3. The value of the Angstrom indicator increases with growth of temperature. And the inclination coefficient in this dependence equals 0.073 on 1°C. It is shown that the Angstrom indicator decreases with growth of the aerosol extinction coefficient for submicron fraction of particles. The maximum hourly average values of the Angstrom indicator are observed in morning and day time, the minimum values - in evening and night time.
