  1. Use of L2P data in the MERSEA analyses WP2.2 partners: H. Heiberg and S. Eastwood (Met.no), L.Santoleri(CNR), E. Autret and J.-F. Piolle (Ifremer), P. Le Borgne, F. Orain, A. Marsouin, H. Roquet (MF/CMS) A.Coat, Y.Guichoux (Actimar) • Mersea Analyses (L4) • The CMS/IfremerMERSEA chain • Operational bias correction • Concluding remarks - Future plans DP/CMS/R&D Medspiration Villefranche Nov. 2006

  2. L4 SST products in Mersea • (GOS) Mediterranean analysis (daily, 1/16°horizontal resolution) • (Met.no) High Latitude analysis (daily, 0.02° horizontal resolution) • (M-F/CMS) Atlantic analysis (daily, 0.05° horizontal resolution) • (IFREMER) Global analysis (daily, 0.1° horizontal resolution, replacing M-F/CMS global analysis) Present status: operational or experimental routine production

  3. GOS analysis

  4. (Met.no) High Latitude analysis

  5. (Ifremer) Global analysis (M-F) Atlantic analysis

  8. Collated(Atlantic) Composites of all L2Ps available over the Atlantic between26/11/06 1200 UTC and 27/11/06 1200 UTC

  9. CollatedAVHRR17_G(Global)

  10. Super collated Atlantic Composite of all corrected collated filesavailable over the Atlantic for a given day

  11. Super collated Atlantic:data origin

  12. The CMS IFREMER MERSEA chain L2P (X) L2P (AATSR) Native Collated Native Collated Correction Corrected collated Super collated Analysed field (L4)

  13. Daily differences to AATSR Can we use the AATSR as a reference?

  14. Using AATSR as a reference?1)We want to correct for regional biases2) Compositing differences over several days shows promising results

  15. Daily bias correctionanalysis of 20 daily differences

  16. Daily bias correction confidence

  17. Is the correction efficient ?

  18. Super collated data origin GOES12 AVHRR18 TMI AVHRR17 AATSR

  19. Super collated SST over the Gulf of Mexico

  20. Super collated bias correction

  21. Future work (at CMS) • Inputs: Inclusion of MODIS, METOP • Method: Improvement of the diurnal warming filtering Correction method: implementation of control statistics • Outputs: Operational delivery of L4, supercollated, collated products

  22. Concluding remarks • L2Psare now widely used as THE SST products • But: • L2Psare sometimes not available in time (Ancillary data may be problematic:NAAPS, NWP,…): We need a Real Time L2P core • L2Psare sometimes not available at all - The duplication of datasets between MISST and MEDSPIRATION should stop - The L2P flow must become fully operational

  23. Future plans • - EUMETSAT L2Ps (OSI SAF CDOP) • METOP • New Geostationary satellite processing lines • NPP/NPOESS (regional) • Sentinel 3 (?) • From Mersea to Marine Core Services (TAC) • (what should it be?) • European GDAC • Validation responsibilities • Maintaining a competence in SST product merging • (collated data production?) • Global and regional L4 production

  24. METOP: First SST products (30/11/06) MAROC
