Description IMS stands for the Interactive Multisensor Snow and Ice Mapping System.
“This data set provides maps of snow cover and sea ice for the Northern Hemisphere from February 1997 to the present from the United States National Ice Center (USNIC).” from the National Snow and Ice Data Center (NSIDC)
- Recommended use
“The IMS product is considered an operational product” from NSIDC
“Accurate monitoring of global snow and ice cover is a key component in the study of climate and global change as well as daily weather forecasting.” from NSIDC
This is used as observation data in both research and operations.
