L4 SST products in Mersea
  • (GOS) Mediterranean analysis (daily,
    1/16horizontal 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)

15
Daily differences to AATSR
Can we use the AATSR as a reference?
16
Using AATSR as a reference?1) We want to
correct for regional biases2) Compositing
differences over several days shows promising
results

Is the correction efficient ?

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

24
Concluding remarks
  • L2Ps are now widely used as THE SST products
  • But
  • L2Ps are sometimes not available in time
    (Ancillary data may be problematicNAAPS, NWP,)
  • We need a Real Time L2P core
  • L2Ps are sometimes not available at all

- The duplication of datasets between MISST and
MEDSPIRATION should stop
- The L2P flow must become fully operational
25
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
