Arctic Snow Cover Information for Hydrological Investigations at Various Scales

Routine snow survey and snow gauge data provided by weather stations establish snow-on-the-ground and snowfall time series but they lack a spatial dimension. Of particular importance to arctic hydrology is the end-of-winter snow conditions. For micro-scale investigations of spring breakup, slope runoff generation or gully sediment production, detailed mapping of the late winter snow cover is required. On a meso-scale, terrain exerts the …
