NSIDC-0271 Richard Armstrong, Mary Jo Brodzik, Ken Knowles, Matt Savoie 20050531 Boulder, Colorado USA NSIDC: National Snow and Ice Data Center http://nsidc.org/data/nsidc-0271.html This data set comprises global, monthly satellite-derived Snow Water Equivalent (SWE) climatologies from November 1978 through May 2007, with periodic updates released as resources permit. Global data are gridded to the Northern and Southern 25 km Equal-Area Scalable Earth Grids (EASE-Grids). Global snow water equivalent is derived from Scanning Multichannel Microwave Radiometer (SMMR) and selected Special Sensor Microwave/Imagers (SSM/I). Northern Hemisphere data are enhanced with snow cover frequencies derived from the Northern Hemisphere EASE-Grid Weekly Snow Cover and Sea Ice Extent Version 2 data (these data were not produced for the Southern Hemisphere). These data are suitable for continental-scale time-series studies of snow cover and water equivalent. The data are binary data files and PNG images, and are available via FTP. scientific research Richard Armstrong, Mary Jo Brodzik, Ken Knowles, Matt Savoie 20050531 Boulder, Colorado USA NSIDC: National Snow and Ice Data Center http://nsidc.org/data/docs/daac/nsidc0271_ease_grid_swe_climatology.gd.html 19780101 20071231 publication date Complete Unknown -180 180 90 -90 NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Cryosphere > Snow/Ice > Snow Cover EARTH SCIENCE > Cryosphere > Snow/Ice > Snow Water Equivalent EARTH SCIENCE > Terrestrial Hydrosphere > Snow/Ice > Snow Cover EARTH SCIENCE > Terrestrial Hydrosphere > Snow/Ice > Snow Water Equivalent None NASA Global Change Master Directory (GCMD) Instrument Keywords AVHRR > Advanced Very High Resolution Radiometer SMMR > Scanning Multichannel Microwave Radiometer SSM/I > Special Sensor Microwave/Imager NASA Global Change Master Directory (GCMD) Platform Keywords NIMBUS-7 NOAA POES > NOAA Polar Orbiting Environmental Satellites SATELLITES ISO 19115 Topic Categories climatologyMeteorologyAtmosphere None Climatology EASE-Grid Global Historical Climatology Northern Hemisphere SMMR Southern Hemisphere SWE NASA Global Change Master Directory (GCMD) Location Keywords Geographic Region > Global 4 NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Cryosphere > Snow/Ice > Snow Cover NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Cryosphere > Snow/Ice > Snow Water Equivalent NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Terrestrial Hydrosphere > Snow/Ice > Snow Cover NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Terrestrial Hydrosphere > Snow/Ice > Snow Water Equivalent Data access is unrestricted, but we recommend that users register before accessing the data.
