Enhanced Historical Monitoring of Snow Cover Across Northern Hemisphere Lands

This proposed two-year effort entitled 'Enhanced historical monitoring of snow cover across Northern Hemisphere lands' intends to generate an improved satellite climate data record of weekly snow cover extent, a dataset of carefully selected station snow cover observations extending well back into the 20th century, and a suite of snow cover

indicator products using both satellite and station data. Project efforts will lead to improved understanding of snow cover variability and trends at higher spatial and longer temporal scales than previously available. Data and products generated through this initiative will serve user communities interested in assessing climate variability and

change, understanding the role of snow in the climate system, verifying snow as depicted in climate models, and for applied studies in water resources, energy, engineering and other fields.
