NSIDC-0079 Josefino Comiso 20000201 Bootstrap Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I-SSMIS 2 Boulder, Colorado USA NSIDC: National Snow and Ice Data Center http://nsidc.org/data/nsidc-0079.html This sea ice concentration data set was derived using measurements from the Scanning Multichannel Microwave Radiometer (SMMR) on the Nimbus-7 satellite and from the Special Sensor Microwave/Imager (SSM/I) sensors on the Defense Meteorological Satellite Program's (DMSP) -F8, -F11, and -F13 satellites. Measurements from the Special Sensor Microwave Imager/Sounder (SSMIS) aboard DMSP-F17 are also included. The data set has been generated using the Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) Bootstrap Algorithm with daily varying tie-points. Daily (every other day prior to July 1987) and monthly data are available for both the north and south polar regions. Data are gridded on the SSM/I polar stereographic grid (25 x 25 km) and provided in two-byte integer format. Data are available via FTP. Important: The most recent revision (Version 2, released September 2007) has tie-points adjusted to be consistent with the AMSR-E Bootstrap algorithm. This involved a complete reprocessing of the entire SMMR-SSM/I time series. Because Version 2 is inter-calibrated with AMSR-E, it is NOT consistent or compatible with the original version of this data set (Version 1). Users should acquire the entire Version 2 data set in order to update their time series. scientific research Josefino Comiso 20000201 Bootstrap Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I-SSMIS Boulder, Colorado USA NSIDC: National Snow and Ice Data Center http://nsidc.org/data/docs/daac/nsidc0079_bootstrap_seaice.gd.html 19781026 Unknown publication date In work Unknown -180 180 90 -90 NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Cryosphere > Sea Ice > Sea Ice Concentration EARTH SCIENCE > Cryosphere > Sea Ice > Sea Ice Concentration EARTH SCIENCE > Cryosphere > Sea Ice > Sea Ice Concentration EARTH SCIENCE > Oceans > Sea Ice > Sea Ice Concentration EARTH SCIENCE > Oceans > Sea Ice > Sea Ice Concentration EARTH SCIENCE > Oceans > Sea Ice > Sea Ice Concentration NASA Global Change Master Directory (GCMD) Project Keywords EOSDIS > Earth Observing System Data Information System ESIP > Earth Science Information Partners Program NASA Global Change Master Directory (GCMD) Instrument Keywords SMMR > Scanning Multichannel Microwave Radiometer SSM/I > Special Sensor Microwave/Imager SSMIS > Special Sensor Microwave Imager/Sounder NASA Global Change Master Directory (GCMD) Platform Keywords DMSP 5D-2/F11 > Defense Meteorological Satellite Program-F11 DMSP 5D-2/F13 > Defense Meteorological Satellite Program-F13 DMSP 5D-2/F8 > Defense Meteorological Satellite Program-F8 DMSP 5D-3/F17 > Defense Meteorological Satellite Program-F17 NIMBUS-7 ISO 19115 Topic Categories climatologyMeteorologyAtmosphere None Antarctic Arctic Bootstrap Algorithm BRIGHTNESS TEMPERATURES Defense Meteorological Satellite Program DMSP NIMBUS-7 Sea Ice Concentration SMMR SSM/I SSMIS Time Series NASA Global Change Master Directory (GCMD) Location Keywords Continent > Antarctica Continent > North America > Canada > Hudson Bay Geographic Region > Arctic Geographic Region > Polar Ocean > Arctic Ocean Ocean > Arctic Ocean > Barents Sea Ocean > Atlantic Ocean > North Atlantic Ocean > Davis Straight Ocean > Atlantic Ocean > North Atlantic Ocean > Gulf Of St Lawrence Ocean > Indian Ocean Ocean > Pacific Ocean Ocean > Pacific Ocean > North Pacific Ocean > Bering Sea Ocean > Pacific Ocean > North Pacific Ocean > Sea Of Okhotsk Ocean > Southern Ocean > Bellingshausen Sea Ocean > Southern Ocean > Ross Sea Ocean > Southern Ocean > Weddell Sea 6 NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Cryosphere > Sea Ice > Sea Ice Concentration NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Cryosphere > Sea Ice > Sea Ice Concentration NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Cryosphere > Sea Ice > Sea Ice Concentration NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Oceans > Sea Ice > Sea Ice Concentration NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Oceans > Sea Ice > Sea Ice Concentration NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Oceans > Sea Ice > Sea Ice Concentration None None NSIDC User Services National Snow and Ice Data Center mailing
