  1. Global Land Ice Measurements from Space (GLIMS), and the GLIMS Data Base at NSIDC: Greg Scharfen U.S. National Snow and Ice Data Center scharfen@kryos.colorado.edu R.Barry, V.Troisi, SJS.Khalsa, R.Weaver, B.Raup PODAG Meeting September 27, 1999

  2. Global Land Ice Measurements from Space (GLIMS) • Expected GLIMS Products • glacier length • area • boundaries • topography • snowline elevation • surface velocity vectors

  3. GLIMS Institutions • USGS Flagstaff • GLIMS Coordination Center • USGS Sioux Falls (EDC DAAC) • ASTER and Landsat image archive • NSIDC • GLIMS World Data Archive • Regional Centers and Stewards • GISS • validation of cryosphere in GCMs • U of NebraskaOmaha • GLIMS Processing Center

  4. GLIMS Data Base at NSIDC:“GLIMS World Data Archive” • Development Activities: • host data base content advisory group • develop functional requirements for data base (with GCC) • design and implement data base (with GCC) • design and implement web-based data submission and user query

  5. GLIMS Data Base at NSIDC:“GLIMS World Data Archive” • Operational Activities: • archive glaciological data derived from the imagery by the regional centers • provide web-based user services for GLIMS-derived data • provide reports on data submission and user activity to GCC • liaise with GCC re. image collection schedule • report on scientific significance of data archive (with GCC, EDC and RCs)

  6. GLIMS Data Base at NSIDC:“GLIMS World Data Archive” • Assumptions: • Terra ASTER operations successful • ECS operations successful • funding initiative successful

  7. GLIMS Data Base at NSIDC:funding request summary • 3 year proposal to NASA 9/99 • joint with Flagstaff, EDC and GISS • based on interagency meeting 6/99 • NASA, NSF, NOAA, USGS • NSIDC budget highlights (yearly): • 1.2 FTE • 18K hardware, 10K software • 14K travel

  8. GLIMS Data Base at NSIDC:User Interface • COTS-based data base • COTS-based web-based search and order GUI • link to ECS for ordering ASTER data from EDC? • Cross reference to image ID • generate subscription
