IRMCR3 Allen, Chris 20111109 Boulder, Colorado USA NSIDC DAAC: NASA DAAC at the National Snow and Ice Data Center http://nsidc.org/data/irmcr3.html The NASA IceBridge MCoRDS L3 Gridded Ice Thickness, Surface, and Bottom (IRMCR3) data set contains products from depth sounder measurements over Greenland and Antarctica taken from the Multichannel Coherent Radar Depth Sounder (MCoRDS). Products include flightlines, boundaries, grids, preview images, and crossover analysis. The data were collected as part of Operation IceBridge funded campaigns, and are stored in Comma Separate Value (CSV), Portable Network Graphics (PNG), Tag Image File Format (TIFF), Tiff World File (TFW), and ArcGIS shape files, and are available via FTP for periodic, ongoing campaigns from 2010 to the present, with additional 1995 to 2011 composite Greenland data. scientific research Allen, Chris 20111109 Boulder, Colorado USA NSIDC DAAC: NASA DAAC at the National Snow and Ice Data Center http://nsidc.org/data/docs/daac/icebridge/irmcr3/index.html 19950101 Unknown publication date In work Unknown -180 180 90 -90 NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Cryosphere > Glaciers/Ice Sheets > Glacier Elevation/Ice Sheet Elevation EARTH SCIENCE > Cryosphere > Glaciers/Ice Sheets > Glacier Thickness/Ice Sheet Thickness EARTH SCIENCE > Cryosphere > Glaciers/Ice Sheets > Glacier Topography/Ice Sheet Topography NASA Global Change Master Directory (GCMD) Project Keywords OIB > Operation Ice Bridge NASA Global Change Master Directory (GCMD) Instrument Keywords RADAR ECHO SOUNDERS NSIDC MCoRDS > Multichannel Coherent Radar Depth Sounder NASA Global Change Master Directory (GCMD) Platform Keywords AIRCRAFT DC-8 > Douglas DC-8 NSIDC P-3B > Lockheed P-3B Orion ISO 19115 Topic Categories elevation geoscientificinformation None Bedrock Topography IceBridge Ice Surface Elevation Ice Thickness NASA NSIDC NSIDC DAAC Radar Echo Sounders Surface Elevation Topography NASA Global Change Master Directory (GCMD) Location Keywords Continent > Antarctica Continent > North America > Greenland 3 NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Cryosphere > Glaciers/Ice Sheets > Glacier Elevation/Ice Sheet Elevation NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Cryosphere > Glaciers/Ice Sheets > Glacier Thickness/Ice Sheet Thickness NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Cryosphere > Glaciers/Ice Sheets > Glacier Topography/Ice Sheet Topography None None NSIDC User Services National Snow and Ice Data Center mailing
