  10. Data, value added Useful products • Passive microwave  ice/snow extent  cloud discrimination, snow • Sea ice Tools • Swath to grid • Subsetting and ordering Educational • Web • CD MODIS, March 22, 2004. Snow = red, cloud = blue. ASF-NSIDC User Working Group Meeting, June 2004

  11. Data management: NOAA World Data Center – Glaciology • Core function since 1976 • Facilitates access to international data NOAA at NSIDC • Operational snow cover model output • Sea ice index • Historic photos and maps Gaining insight, NASA  NOAA shift for long-term data management NOAA at NSIDC ASF-NSIDC User Working Group Meeting, June 2004

  12. Data management: NSF IARC - Frozen Ground Data Center • Circumpolar Active-Layer Permafrost System (CAPS) CD-ROM • IPA Global Geocryological Data (GGD) system (metadata) ARCSS Data Coordination Center • Arctic System Science (ARCSS) • Data from NSF funded research ASF-NSIDC User Working Group Meeting, June 2004

  13. Data management: NSF, cont. Antarctic Glaciological Data Center • Data collected by the US Antarctic Program • PI contributed data • Compiled data sets U.S. Antarctic Data Coordination Center • Info to the Antarctic Master Directory of the Global Change Master Directory ASF-NSIDC User Working Group Meeting, June 2004

  14. Data users, 1997-2003: Other Commercial Government K - 12 Research & Higher Ed As processed by User Services. ASF-NSIDC User Working Group Meeting, June 2004

  15. Research at NSIDC Overview: • 12 resident scientists • Visiting scientists • 35 grants • NASA and NSF dominant ASF-NSIDC User Working Group Meeting, June 2004

  16. September 2002 September 2003 Sea ice extent and concentration anomalies relative to 1988-2000 Research: Cryosphere & climate • Arctic climate • Sea ice • Data products for modeling • Water budget • Historic time series for the arctic ASF-NSIDC User Working Group Meeting, June 2004

  17. Research: glaciers, sea ice, ice sheets • Mega dunes • Sea ice melt ponds • Sensors & sea ice concentrations • Glacier mass balance Antarctic mega dunes, field work Arctic sea ice break up Taku Glacier, 1929 ASF-NSIDC User Working Group Meeting, June 2004

  18. Research: Snow, permafrost, frozen ground • Passive microwave • Snow water equiv. • Snow cover • Frozen ground • Arctic hydrology & water budgets • Cold lands processes • Surface to satellite scale Fresh crack in permafrost causing block disintegration, Kondratyeva.

  23. Web: Top user domain names Unknown = no IP address w/in 10 sec. ASF-NSIDC User Working Group Meeting, June 2004

  24. Part III: Restructuring Responding to growth Looking ahead

  25. Growth Staff: from 20 to 70 in 15 years • 12 scientists • 13 program/project • 42 services (computer, data, writers,etc.) • 5 administrative • 5-10 students • 2-5 visiting scientists ASF-NSIDC User Working Group Meeting, June 2004

  26. Selected issues noted • Unclear lines of authority & responsibility • Tasks and priorities not coordinated • Perception of low accountability • Overlap of program and center level functions • No short-term operational plan • Center-wide strategic plan not well established ASF-NSIDC User Working Group Meeting, June 2004
