Виноградова Институт географии РАН, Москва, Россия *ttitkova@yandex.ru Snow occurrence time on the Russia’s territory in the early 21st century (from satellite data) T.B. <...> Vinogradova Institute of Geography, Russian Academy of Sciences, Moscow, Russia *ttitkova@yandex.ru Received April 8, 2016 Keywords: climatic parameters, MODIS, snow cover, snow coverage. <...> Summary Time of the snow cover appearance, existence and disappearance on the Russia’s territory in the early 21st century (2000–2015) was corrected using the MODIS/Terra satellite data (the 8-day discreteness, and the 0.5Ч0.5° resolution). <...> The relationship between the snow cover characteristics and the climate ones was investigated using data obtained at the ground-based stations together with correlation between dates of snow appearance and loss and the climate parameters. <...> Significant coefficients of correlation (the Student criterion of probability was equal to 0.95) were found between time of the snow cover presence and dates of the temperature drop below 0 °С and the amount of days with negative temperatures. <...> Changes in the climate characteristics result in that due to decreasing of the solid precipitation in winter time the snow presence duration becomes shorter over the European part of Russia and in the Western Siberia. <...> Поступила 8 апреля 2016 г. Принята к печати 12 октября 2016 г. Ключевые слова: климатические показатели, MODIS, продолжительность залегания снега, снежный покров. <...> Оценена погрешность определения параметров снежного покрова в осенний и весенний периоды по спутниковым данным MODIS путём сравнения <...>
