Snow and Ice Cover
Snow and Ice Cover
Description: The cryosphere (areas covered by ice, snow, glaciers, or permafrost) is an extremely dynamic part of the global system. Changes in the seasons and climate bring great changes to the expanse of Earth's cryosphere. Satellite data allows scientists to keep a constant eye on these areas.

Infrared and microwave data from multiple satellites including the NOAA's GOES Imager and POES AVHRR, US Air Force DMSP/SSMI, and EUMETSAT MSG/SEVIRI sensors is combined to create these daily maps of global snow and ice cover of the planet. The use of multiple datasets provides relatively high spatial resolution (about 4 km/pixel) daily maps in all weather conditions. Light blue areas indicate sea ice extent; white colors indicate all other areas covered in snow.
