Project Description

Large-scale high resolution (1-4 km) estimates of snowpack properties – Snow Cover Area (SCA), Snow Water Equivalent (SWE) and Snow Depth (SD) – over seasonal snow-covered land are needed as inputs to weather, climate and hydrological prediction models. Snow monitoring products that are most frequently used at NOAA, IMS snow charts and USAF SNODEP analysis, have shortcomings in temporal consistency, coverage and/or spatial resolution. The primary goal of the project consists in the improvement of the snow cover characterization and in the development of a new enhanced global snow cover dataset using available remote sensing data.

The new dataset will include global information on three major snow cover properties: The snow cover extent, snow water equivalent and on the snow depth. The developed retrieval algorithm provides fully automated processing and interpretation of satellite observations combined with  snow reports from ground-based weather stations.  All snow products will be generated daily at 4 km spatial resolution. The data processing effort incorporates satellite and surface observations since 1987 and thus will result in creation of a climate-grade snow dataset spanning over more than three decades. The new snow retrieval system will be prepared for operational implementation and further operational use at NOAA NESDIS

Completion of the project is expected in 2023.
