The most recent snow cover information is given below. They are generally 1-4 days old. Hover over a thumbnail to get the full image, description, and credits. Important: The products shown on the "Cryosphere Now" pages provide a variety of perspectives on the state of the cryosphere. They are for purposes of illustration and comparison and are not necessarily endorsed by GCW as "authoritative". Note: Some of the products are not available in during the summer.
NOAA Multisensor Snow/Ice Cover
The Global Snow and Ice Cover Map is derived from combined observations of METOP AVHRR, MSG SEVIRI, GOES Imager and DMSP SSMIS. The algorithm is fully automated. This is an experimental product. It is a NOAA/NESDIS product. (Courtesy of Peter Romanov)
The GCW/FMI SWE Tracker is a product of the Finnish Meteorological Institute (FMI), based on GlobSnow snow water equivalent (SWE). It was developed as part of the GCW Snow Watch project. It illustrates the current Northern Hemisphere snow water equivalent relative to the long-term mean and variability.
EC/GCW NH Snow Extent Tracker
The Environment Canada (EC) GCW Snow Cover Extent Tracker provides an estimate of the current Northern Hemisphere snow cover extent relative to the 1998-2011 period based on the Canadian Meteorological Centre operational daily snow depth analysis. The analysis uses real-time surface snow depth observations and model-derived information. More information, and trackers for North America and Eurasia, are available at the Canadian Cryospheric Information Network.
EC/GCW NH SWE Tracker
The Environment Canada (EC) GCW Snow Water Equivalent Tracker provides an estimate of current Northern Hemisphere SWE relative to the 1998-2011 period. It is based on the Canadian Meteorological Centre operational daily snow depth analysis with SWE estimated using a density look-up table. The CMC analysis uses surface real-time snow depth observations and model-derived information. More information, and trackers for North America and Eurasia, are available at the Canadian Cryospheric Information Network.
Rutgers Daily Snow Departure
The Rutgers Global Snow Lab, Rutgers University, generates many snow products. This is the daily IMS snow cover departure from the long-term average. Text annotations were added here.
IMS Snow Cover
IMS is the Interactive Multi-Sensor Snow and Ice Mapping System from the National Ice Center.
