Abstract: A movie presentation has been prepared by the Hydrological Sciences Branch of NASA/Goddard Space Flight Center in order to increase awareness of the potential of microwave remote sensing for snow studies within the scientific community. This 12-minute movie offers some background information on snow hydrology and remote sensing of snow, and explains how passive microwave remote sensing is used to derive measurements of snow cover and snow depth. A three-year time series of monthly SMMR data is shown while the narrator discusses the observed brightness temperature patterns. Seeing the monthly microwave data in a time series allows the viewer to gain an appreciation of the large variability that is present in the Northern Hemisphere snowcovered area. Although more difficult to interpret, gross snow depth changes are also obvious in the film sequence. The compilation of microwave satellite imagery should complement the existing visible satellite data set and be a useful reference for climatological and energy balance studies.
