9.6 Snow and Ice Products
Meteorologists and climatologists are interested in short- and
long-term observations of snow and ice cover because of its affect
on weather forecasting and climatic processes. Snow and ice
analysts in the National Oceanic and Atmospheric Administration's
(NOAA) National Environmental Satellite, Data, and Information
Service (NESDIS) have been creating weekly maps showing the extent
of snow cover for the Northern Hemisphere since 1966. The snow and
ice maps, from 1966 to 1999, were produced weekly at a spatial
resolution of 190 kilometers (km). The Interactive Multisensor Snow
and Ice Mapping System (IMS) replaced the weekly mapping process in
June 1999 and improved the snow and ice map by producing daily maps
at 23 km resolution.
