  1. The Activities of Andrea Kaiser-Weiss GHRSST Project Officer, based at NCEO, University of Reading, UK since August 2010 NASA SST meeting Seattle 9th Nov 2010

  2. Outline • Pre-requisites of data merging and how addressed in GHRSST • Related European activities • GHRSST in the international landscape • Summary

  3. Pre-requisites of Data merging • Standardisation of formats (GDS2) – progress of GDS2 implementation (DAS-TAG) . • Data merging requires quality flags and error estimates : SSES (ST-VAL) and bias removal • Physical approach requires developments of retrieval methods (EarWig) . • Data merging requires handling diurnal variability (DVWG) . • Special problems in High latitudes (HL-TAG) .

  6. GHRSST R/GTS framework Donlon et al, 2007

  7. Outline • Pre-requisites of data merging and how addressed in GHRSST • Related European activities - ERNESST - CCI (see Chris) - OSI-SAF - MyOcean 3. GHRSST in the international landscape 4. Summary

  8. ERNESST European Research Network for Estimation from Space of Surface Temperature: • Retrieval techniques • Clouds • Diurnal variability • Integrating different satellites and in situ • Interaction with NASA-SST wanted

  9. NEWS (from Pierre Le Borgne) Short term: The new Geostationary OSI SAF SST chain is expected to be operational in January 2011 Cloud mask control flagging dubious pixels A bias correction method is being implemented Files are GDS V2 compliant Delivery to Beta Users in November 2010 Experimental products (OE SST, sdi, DW, fronts) available progressively in 2011 Longer term: Preparation of the OSI SAF CDOP2 (next contract with EUMETSAT): 2012-2017 Bias correction/OE applied to METOP/AVHRR All SEVIRI data reprocessed with the new chain

  10. Error simulation Analyzed SST(OSTIA) Retrieved (predicted) SST ECMWF profiles + RTTOV Operational algorithm Applied on simulations Retrieved – analyzed SST = Predicted algorithm error (used as a correction term) Simulated BTs

  11. Biases improved with the new algorithm Cause: atmospheric water vapour Le Borgne, P., Roquet, H. & C.J. Merchant, Estimation of SST from the SEVIRI, improved using numerical weather prediction, Remote Sensing of Environment,115, 55–65, 2011. Before: After:

  12. News fromMyOcean L3 (Europe)

  13. MyOcean QC/Validation • MyO V1 (Dec 2010, see myoceanservice@ifremer.fr) • Minimum QC/validation service • black list (as is) • L2P minimum list QC and validation • All L3 + L4 • HR/DDSV1 • Issues • MyO V1 Outputs will be delivered in preGDS2 format • MyO will have to cope with inputs in GDS1 and GDS2 formats: Any provider please send us your transition to GDS2 planning, Thanks!

  16. Outline • Pre-requisites of data merging and how addressed in GHRSST • Related European activities • GHRSST in the international landscape - CEOS-VC - User communities 4. Summary

  17. 3. GHRSST in the international landscape GHRSST = independent, and well linked to the national and international space agencies, Met-offices, and major research institutes (e.g. Navoceano, NOAA) GHRSST interaction with NASA SST Science Team, ERNESST, ESA CCI, MyOcean, Australia, Japan, and others. Links to GCOS, CEOS, JCOMM, WCRP, OceanView, ET-OOFS, DBCP, Argo

  18. GHRSST serving as CEOS SST-VC • Improve coordination, consolidation and development of the collective EO SST capability • Improve SST products, services and their dissemination with better user engagement • Avoid duplication of existing activities by using the well established GHRSST as the prime implementation mechanism.

  19. GHRSST Applications and User support (AUS-TAG) User communities: SST related research (ocean/atmosphere/coupling) Ocean modelling and forecasting NWP (hurricanes, seasonal-interannual rainfall variability) Climate variability and change Ecosystems (habitats, marine agriculture) Fisheries Navy acoustic signal processing

  20. Users and GHRSST’s responsibility The Advisory committee noted that there are now more users than ever before and advised GHRSST that care was needed to serve this user community well. • GHRSST is now focussing on documentation, products and services, which are easy to access, useful and well maintained

  21. User tools and Services • NAIAD and dataminer • IFREMER and JPL • SQUAM • GMPE • HRDDS • WMS • G1 OurOcean • DataCasting

  22. GHRSST XII Science Team meeting 2011 Edinburgh, Scotland, 27 June - 01 July Special emphasis is on facilitating the exchange between data users and producers. Please indicate your interest by sending an email to ghrsst-edinburgh2011@reading.ac.uk

  23. Summary GHRSST has strong overlap with NASA SST (ongoing and new) and collaboration is highly desirable. GHRSST will work towards community consensus on SST issues. NASA SST meeting Seattle 9-12 Nov 2010
