Evaluation Of Northern Hemisphere And Regional Snow Extent Products Within Esa Snowpex-Project

The major results and findings made during the ESA SnowPEx project concerning the evaluation of the Earth Observation-based moderate resolution snow products is presented. Both the Northern Hemisphere (NH) Snow Extent (SE) daily products as well a few regionally available products by different data providers are addressed. Comparison against daily at-ground observed Snow Depth is made, after first converting all the snow products and the in situ observations to binary 'snow/no-snow' information. We first introduce the datasets employed in the analyses, then describe the applied methodology and finally present the major findings obtained.
