Apr 6, 2021 · GMASI utilizes data from various satellite sensors in visible, infrared, and microwave bands to create daily global snow and ice maps. The system includes METOP-B/C AVHRR, GPM GMI, and GCOM-W1 AMSR2. These 2-km resolution maps cover the entire globe on a 9000 x 18000 grid and are provided in NetCDF and GRIB2 formats.
The snow depth measures the depth of recently accumulated dry snow, which varies from 0 to 400 with accuracy of 1 mm. The product is updated once per day at 4 am EST. This product is originally generated by Fleet Numerical Meteorology and Oceanography Center (FNMOC).
Dec 11, 2020 · U.S. and Northern Hemisphere Snow Cover. Snow cover extent in the U.S. and the rest of the Northern Hemisphere is mapped from satellite observations. Current and recent snow-cover graphics are available here.
Jan 12, 2018 · Ice products have two primary operational uses: navigation and numerical weather prediction (NWP). At present, their use in NWP is limited. Snow products are used in NWP. Both snow and ice products are important in climate studies. Key Users. National Ice Center (NIC) Alaska Sea Ice Program (ASIP) Naval Oceanographic Office (NAVOCEAN)
May 16, 2018 · Snow products are used to better understand the hydrologic cycle and to determine areas that have the potential for disastrous flooding. They are used for numerical weather prediction and climate monitoring. Sea ice products are important to ocean navigation and for studying climate change.
7 Day 30 Day 60 Day. U.S. National Ice Center's Interactive Multisensor Snow and Ice Mapping System (IMS) section for daily Northern Hemisphere snow and ice products.
Snow Cover Maps. How much of the Northern Hemisphere is covered with snow and ice today? How has that changed over the satellite record? Daily maps, charts, and animations show the extent of snow and ice over the contiguous United States, Alaska, or the whole Northern Hemisphere.
