In the mid/high latitudes during cold seasons, a substantial portion of precipitation
falls in the form of snow. Falling snow has been one of the last great
unkonwns for the hydrological water cycle and radiation budget analyses in
climate and weather researches. Given their extensive spatial and temporal
coverage, satellite-based remote sensing methods are uniquely suited for
global snowfall observations. However, in spite of tremendous developments
in meteological satellite technology over the past several decades, developing
satellite remote sensing techniques to provide accurate snowfall...
