The low clouds conditions over the territory of the Siberian region are researched, using the 47-year (1966-2012) observation data of 25 meteorological stations. The spatial distribution of the seasonal average values of the amount of low-level clouds and their frequency according to five gradations (amount of clouds: 0, 1-3, 4-6, 7-9, and 10), as well as the cloud base heights and its standard deviations was analysed for four seasons (winter, spring, summer, autumn).
