14 Perros-Guirec, June 2008 OSTIA Reanalysis Project Goals 1.Provide a consistent time series of OSTIA data going back to the earliest available AVHRR data with error estimates. 2.Will use a system which closely resembles the current operational OSTIA. Relevant Graphic Current Status 1.Preparing data (including error estimates) Sea ice from OSI SAF [Done 1987-]Sea ice from OSI SAF [Done 1987-] Pathfinder [Can read HDF data]Pathfinder [Can read HDF data] (A)ATSR(-1/2) [L2P data with ESA](A)ATSR(-1/2) [L2P data with ESA] AMSRE (Use RSS data)AMSRE (Use RSS data) 2.Preparing background errors, running short tests. Looking Forward 1.OSTIA to provide high resolution information to add to HadISST-2. 2.Include more satellites (TMI / SEVIRI / GOES / MTSAT / AVHRR-LAC). John Stark, UK Met Office

15 Perros-Guirec, June 2008 Daily OI Version 2 Project Goals 1.Produce Daily OI on 1/4 o spatial grid Include satellite bias correction with respect to in situ dataInclude satellite bias correction with respect to in situ data 2.Compute analysis for entire period with satellite data 3.Make product useful for climate Current Status 1.Uses AVHRR + In Situ Data January presentJanuary present 2.Uses AMSR + AVHRR + In Situ Data June presentJune present 3.Interim (1 day of data) and final (3 days of data) versions 4.Ship SSTs corrected using buoy SSTs Looking Forward 1.Version2 becomes operational 2.Add ATSR and TMI 3.Use Pathfinder NOAA-7 data when available AVHRR-only AMSR+AVHRR Anomaly SST Impact from Hurricane Katrina Dick Reynolds, NCDC

16 Perros-Guirec, June 2008 GHRSST/GCOS SST Intercomparisons Project Goals 1.To understand differences between SST analyses to create better, long- term SST climate data records 2.To link modern satellite-based records with the historical, primarily in situ-based records Current Status 1.Initial products and diagnostics for the satellite era available in netCDF and Matlab at: mp.html (HTTP and FTP) mp.html mp.html 2.Preliminary analysis of differences performed and presented at CLIMAR-III workshop, May 2008 Looking Forward 1.Add further diagnostics Calculate standard diagnostics for each product w.r.t. its own climatology 2.Incorporate historical products (1850 on) into the framework 3.Summarize differences as a set of strengths and weaknesses for each product Tess Brandon, NODC
