Spatially distributed dual frequency (17.2 and 9.2 GHZ) scatterometer observations of shallow tundra snow

Retrieval of snow volume properties at high spatial resolutions has become a priority in hydrological and climatological research. Recent studies have identified the 8 to 18 GHz range as particularly sensitive to snow water equivalent. In this study we present snow target observations using a dual frequency (17.2 GHz and 9.6 GHz) scatterometer system. The observations were collected in a unique tundra environment providing a novel dataset for comparison with in situ snow survey data. Moreover, the scatterometer was sled mounted allowing observations to be collected over a substantial spatial domain.
