Aerosol optical parameters in Kazakhstan for the summer and autumn seasons

Measurements of direct and diffuse solar radiation in cloudless atmosphere were conducted in 1984 and 1996 - 1998 in South-Eastern Kazakhstan (not far from Almaty city) during the period July - October. The day sky spectrophotometer, operating in 8 spectral bands within the interval 0.42 - 22.2 microns, was used. Aerosol phase function was inverted from diffuse radiance in the solar almucantar using proposed earlier adjustment method. Aerosol optical depth was calculated by long Bouguer method for solar zenith angles 30 degree(s) - 80 degree(s) (both a.m. and p.m.) under condition of stability of atmospheric optical transparency during 1 and more hours.
