  1. NOAA’s National ClimaticData Center Thomas Karl Climate Working Group Climate Observations & Analysis Program Review April 11-13, 2007 1

  2. National Climatic Data Center (NCDC) Asheville, North Carolina • NCDC is the steward of the Nation’s in-situ and satellite data and information. • Collocated with the U.S. Air Force and Navy Climatology offices. • The three agencies fulfill much of the Nation’s climate data & information • requirements.

  3. Mission Statement To provide access and stewardship to the Nation’s resource of global climate and weather related data and information, and assess and monitor climate variation and change.

  4. Archive, Access, and AssessmentHighlights: 2006 Safe Storage of more than 2,100 terabytes of climate data • 120 terabytes of data added to the archive in 2006 • 25 terabytes of data delivered monthly to customers via web and ~ 4 million unique user hosts in 2006 • Production/distribution of 5 monthly serial climate publications to more than 100K users Critical Scientific Assessments • Climate Change Science Program (CCSP) Assessments • Weekly/Monthly/Annual “State of the Climate” Reports • International Panel on Climate Change report

  5. Mandated Functions of NCDC’s Mission Acquire and Ingest data Archive and scientific stewardship of the Nation’s meteorological data - national & international Provide access to data, metadata, and products Monitor & describe the national & global climate

  6. Data Received From Many Sources Forecast Warning Analysis NWS Coop Observers Global Synoptic Reports NCEP Charts Ship, Buoy Reports Rocketsonde Radiosonde Storm Data Doppler Radar (GOES, POES, NPOESS, many other) Satellites Aircraft Profiler ASOS USCRN

  7. Data Received on Many Types of Media • Digitally (Now majority of data ingested) • NWS Cooperative Observer Data & Hourly Precipitation Data • Original manuscripts, Punched paper tapes • Small amount of data • Analyzed charts • Original manuscripts • Autographic charts & rolls

  8. Mandated Functions of NCDC’s Mission Acquire & Ingest data Archive and scientific stewardship of the Nation’s meteorological data – national and international Provide access to data, metadata, and products Monitor & describe the national & global climate

  9. Two Basic Archive Considerations #1 Data required by law to be archived Public Law 81-754 (1951): NCDC established as an Agency Records Center for US weather & climate records with responsibilities of archiving & servicing • #2 Long-term economic, societal, and scientific value • Recommendations from: • National Research Council committee reports • Data Archive & Access Requirements Working Group (SAB)

  10. The National Environmental Data Archive – Class Storage (Data Variety and Growth)

  11. Non-Digital Data Archive Percent digitized (Keyed or imaged) 50% (50 million) 1.7% (2,105 reels) 1.0% (8,600 fiche) Manuscript / Autograph* 100 Million Pages stored in 125K boxes * Located at Asheville; additional paper records located at the Federal Records Center in Georgia that will be inventoried and prioritized for digitization 35mm & 16mm Film 125,129 Rolls Microfiche 860K fiche containing 51 million pages

  12. Climate Database Modernization Program: 2000-2006 Over 7 terabytes of Climate data now only a mouse click away • Fifty million weather & environmental images online • Hundreds of million of records digitized & now online • International data access and rescue activities 1842 Hourly Weather Data from Washington, DC Imaged and Digitized through the CDMP Program North Carolina Cooperative Observer Images -Online Missing images 1950-1980 will be available later in 2007 African Records Rescue Project

  13. Mandated Functions of NCDC’s Mission Acquire & Ingest data Archive and scientific stewardship of the Nation’s meteorological data - national & international Provide accessto data, metadata,and products Monitor & describe the national & global climate

  14. Climate Data Access via the Web NEXRAD= Radar CLASS =Currently Satellite NOMADS= Models CDO = Climate In-Situ Climate data access by user type

  15. Climate Data Access NCDC: On the Forefront of E-Business Offline Access (telephone, letters, etc.) Continues to exhibit a sharp decline Online (Web) Access Continues to exhibit a rapid increase

  16. Mandated Functions of NCDC’s Mission Acquire & Ingest data Archive and scientific stewardship of theNation’s meteorological data - national & international Provide access to data, metadata, and products Monitor and describe the national and global climate

  17. Examples of Climate Assessments

  18. Monitor and Describe the Climate Climate Monitoring Web Access (Examples Highlight the Global Products Page)

  19. Tropical Cyclone Intensity Reanalysis NCDC Data Base Build • Reanalysis effort to develop a homogeneous 23-year satellite record • Tropical cyclone intensity historically estimated from “best track” data • many inherent temporal heterogeneities • New data set - from > 20 satellites;14 formats • Removed intra-series & temporal biases • 1983-2005 data: ~169K images; ~2000 storms • Annual update after “Best Track” data released • working to fill in 1981-1983 Example images from New Data set PDI=Power Dissipation Index Combined measure of Frequency & Intensity Univ. of Wis. Analysis Partnership • Objective algorithm develop to work with new data set • Principal components of azimuthally averaged Tb used to estimate intensity • Similar to objective Dvorak technique; valid in all ocean basins • Observed Results • PDI increasing in North Atlantic • No significant global trends • “UWis / NCDC” intensities have little temporal bias
