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

19Is the correction efficient ?

23Future 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
24Concluding 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
25Future 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?)
- Validation responsibilities
- Maintaining a competence in SST product merging
- (collated data production?)
- Global and regional L4 production
