The Global Multisemsor Automated Snow and Ice mapping system
(GMASI)
uses synergy of observations in the visible, infrared amd microwave spectral bands
from operational polar orbititng and geostationary satellites to generate daily global maps of snow and
ice cover. The current version of the system incorporates data from the following satellite sensors:
METOP-A AVHRR, DMSP F-16,-17, -18 and -19 SSMIS, GOES-East and -West Imager, MSG SEVIRI. GMASI global daily
snow and ice maps (images and binary data) are available
here.
