Update on specific development for CMEMS Med-MFC V2 Analysis and Forecast Product 1.Data Assimilation: Grid point EOFs ( * ) (Almost concluded, checks to be performed) Different Observational error for each satellite( * ) (postponed) Use of a new MDT (1993-2012) ( * ) (done) Change in the sign of the DAC to be applied to SLA ( * ) (done) Register of rejected data ( * ): (done) ( * )= as in proposal ( * )= added in V2 DR ( * )= added after V2 DR 2.ECMWF precipitations ( * ): (done) 3.New ECMWF LSM ( * ): (postponed)

3. Data Assimilation Grid point EOFs(*) (Almost concluded, checks to be performed) Some check are in progress in order to mitigate a problem occurred after launching the V2 run. It has been decided to impose the EOFs = 0 at levels deeper than 56. Two solutions are now tested: 1.Use the EOFs created and impose in the code the values to be = 0 for levels deeper than the 56 th 2.Create new EOFs only for the first 56 layers The 2 tests are now running starting from December 2012 and the first one is now integrating October 2014, while the second test has run until July 2013 and the new EOFs needs to be crated for remaining months.

4. Data Assimilation Different Observational error for each satellite(*) (postponed) Test have been performed to check the modification f the observational error for each satellite according to CLS suggestions: Jason2: 2cm Altika: 1cm Cryosat2: 6  4cm

5. Data Assimilation Different Observational error for each satellite(*) (postponed) ALL SATELLITES

6. Data Assimilation Different Observational error for each satellite(*) (postponed) JASON2

7. Data Assimilation Different Observational error for each satellite(*) (postponed) ALTIKA

8. Data Assimilation Different Observational error for each satellite(*) (postponed) CRYOSAT2

9. Data Assimilation Different Observational error for each satellite(*) (postponed) It has been discussed by the Med-MFC consortium and it has been pointed out that: -The values suggested by CLS derive from a study on the Global Ocean and a specific study on the Mediterranean will be performed in the first months of next year -According to this study the error associated to Altika satellite is lower than the one of Jason2 that is considered a more trustable satellite (this aspect should be better investigated) -Comparison with independent tide gauges measurements should be performed -So we would postpone this change for V3 since additional R&D is required before adopting it

10. Data Assimilation Use of a new MDT (1993-2012) (*) (done) Change in the sign of the DAC to be applied to SLA (*) (done) ExpRMSE(cm) sys53.75 s4e4.39 EXP13.77 EXP23.49 NameSLAMDT SYS4E AVISO-DAC (14km) MDT 1993- 1999 EXP1 AVISO+DAC (14km) MDT 1993- 1999 EXP2 AVISO+DAC (14km) MDT 1993- 2013

11. Data Assimilation Change in the sign of the DAC to be applied to SLA (*) (done) It has been discussed by the Med-MFC consortium the possibility to change the DAC sign in the current operational system V1. A Request For Change is under preparation and will be sent to Mercator asking to make changes in the actual V1 system in production from (possibly) 15 December. A second Request For Change that will cover the period July 2013 up to now has been discussed but it has been pointed out that: -It will require some time since also the biogeochemical system should be re-run -Since changes will affect almost the entire timeseries from July 2013 we should deliver new QUIDs and deadlines for V2 Acceptance Review documentations are approaching -The users will be informed of 2 changes in their input data in few months and in addition we will deliver V2 in May 2015 with this changes applied to the long timeseiries.

15. SURFACE TEMPERATURE ECMWF Daily Precipitation (*) (done) VOLUME TEMPERATURE

16. New ECMWF LSM ( * ) (postponed) The actual ECMWF LSM used in the operational system is almost identical to the one evaluated by using a 50% land threshold 3 tests have been performed by modifying the ECMWF land-sea mask: 1.LSM with land threshold = 60% 2.LSM with land threshold = 70% 3.LSM with land threshold = 60% plus removal of additional points with high land-sea temperature difference (>5degC) Validations of the modified masks showed some positive improvements but also some negative skills. It has been decided to postpone this change since this issue needs further investigations (to be discussed the influence of the wind direction)
