Regional features of present winter snow accumulation variability in the North Eurasia from data of observations, reanalysis and satellites

The paper presents data on winter snow accumulation on the Russian territory obtained from different sources: ground measurements of snow depth on meteorological stations, water snow equivalent calculated from data of route surveys, reanalysis, and satellite observations. Three large regions were is...

Description
Summary:The paper presents data on winter snow accumulation on the Russian territory obtained from different sources: ground measurements of snow depth on meteorological stations, water snow equivalent calculated from data of route surveys, reanalysis, and satellite observations. Three large regions were isolated which are distinguished by characters of the snow depth fluctuations and their long-term tendencies. Comparison of the trends calculated from data of reanalysis and satellite measurements demonstrated essential disagreement of them with data of in situ observations. Рассматриваются данные о зимней аккумуляции снега на территории России из разных источников: наземных наблюдений за толщиной снежного покрова на метеостанциях; водного эквивалента снега по данным маршрутной съёмки, а также реанализа и спутниковых измерений. Выделено три крупных района, отличающихся по характеру колебаний толщины снега и их многолетним тенденциям. Сравнение этих трендов, полученных по данным реанализа и спутниковых измерений, указывает на их существенные расхождения с данными наблюдений.
