The cryosphere which are areas covered by ice, snow, glaciers, or permafrost is an extremely dynamic part of our global system. Changes in seasons & climate bring great changes to the Earth's cryosphere.
Infrared (IR) and microwave data from multiple satellites including NOAAs GOES Imager and POES AVHRR, US Air Force DMSP/SSMI & EUMETSAT MSG/SEVIRI sensors are combined to create the daily maps of global snow and ice cover of the planet. using multiple datasets provides relatively high spatial resolution (about 4 km/pixel) daily maps and in all weather conditions. Light blue areas indicate the sea ice extent, white colors indicate all other areas covered in snow.
