Abstract:

The mean characteristics of cloudiness, based on meteorological data for southern Siberia regions, are presented. It is shown that the sky is absolutely clear in 15% of all observed situations; hence, only measuring data on spectral brightness and transparency of the atmosphere for these situations can be used for aerosol radiation modeling. Based on data of cloud observations in Tomsk, the efficiency of AERONET data selection is estimated to exclude the cloudiness situations from the presented spectral brightness series in solar almucantar and vertical position.
