  3. Archive Status • LTSRF Archive Holdings as of Dec 2006 • 1.7 TB (~32 TB uncompressed) spanning 2005 and 2006 • > 8300 accessions (RDAC/Sensor/Level/Date), ~120k files • AMSR-E, AVHRR-16, AVHRR-17, AVHRR-18 (GAC and LAC/HRPT) , MODIS Aqua and Terra, SEVIRI, AATSR, TMI • Coming Soon: GOES, Gridded AMSR-E and TMI

  4. Archive Status • LTSRF Archive Holdings as of Nov 2007 • 8.6 TB (172 TB uncompressed) spanning 1985 through 2007 • 33324 accessions (RDAC/Sensor/Level/Date), 487121 files • AMSR-E, AVHRR-16, AVHRR-17, AVHRR-18 (GAC and LAC/HRPT) , MODIS Aqua and Terra, SEVIRI, AATSR, TMI, GOES, MetOpAVHRR, Gridded AMSR-E and TMI, Two Daily Reynolds OI L4, OSTIA L4 • Plus: automated status reporting, RSS feeds • Coming Soon: ODYSSEA L4, DMI N.Sea L4

  11. Pathfinder Climate Data Records • Pathfinder Version 5 being used extensively in re-analysis products • Reprocessing capability being transferred to NODC • Version 6 will consist of both L2P and L3 products • Uncertainties to be developed similar to MODIS hypercube approach • Improvements to quality tests being evaluated

  12. GCOS SST and SI Working Group • Intercomparison site being populated now: • AVHRR Pathfinder V5, AVHRR Pathfinder V4 • Operational AVHRR • HadSST2 • Kaplan • ERSST, OISSTv2, New Daily OI • Weekly, one-degree and monthly five-degree • Connecting historical SST reconstructions with the satellite record • First phase (all products in GHRSST L4) by Jan 1

  13. Example L4 Re-Analyses • Reynolds Daily OI - Daily 25 km • Two versions, one available back to 1985 using Pathfinder • Improvements under development New OI Using Pathfinder AVHRR New OI Using Pathfinder AVHRR + AMSR-E Dick Reynolds NOAA NCDC

  14. Example L4 Re-Analyses • Met Office OSTIA Reanalysis • Using AVHRR Pathfinder back to 1985 • Inputs compiled in 2008… John Stark and Craig Donlon Met Office, UK

  15. Status of GHRSST L4 Reanalyses RSS

  16. GHRSST Multi Product Ensemble • Effort underway to inter-compare various GHRSST and related L4 products • Based on an ensemble median approach (http://www.ghrsst-pp.org/Todays-global-SST.html) • Currently includes: Met Office OSTIA SST NCEP RTG_SST_HR SST NAVOCEANO NAVO K10 SST observations JMA MGDSST SST RSS RSS MW Fusion SST RSS RSS MW+IR Fusion SST FNMOC GHRSST-PP SST and sea Ice MERSEA ODYSSEA SST NOAA AVHRR OI (Reynolds Daily OI)

  17. Status of GHRSST L2P Reprocessing Version 2 in Spring 2008, ARC Version 3 in 2009 Andy Harris and Eileen Maturi w/ NCDC, in 2008 Pathfinder RSS NOAA Scientific Data Stewardship - Evans, Kilpatrick, and Casey - commenced July 2007 RSS

  18. SST CDR Priorities for 2008 • Initiate OSTIA Reanalysis back to 1985 • Link historical and satellite analyses through intercomparison (both GCOS and GMPE) • Close out Pathfinder V5 for 1985-2007, and include 1981-1984 • Establish initial AVHRR Pathfinder capability at NODC ==> Version 6 • Find a means of creating retrospective MODIS L2Ps • (A)ATSR Version 2
