2. www.argans.co.uk SMOS L2 Ocean Salinity – status, 08/07/2009 New processor 03_07 Operational & prototype still in sync Removed old MIRE Many changes & bug fixes... To be used in DPGS tests next week Updated documentation: OPSRD, PPSRD, ATBD, IODD, DPM...

3. www.argans.co.uk SMOS L2 Ocean Salinity – status, 08/07/2009 New default values -999 New versions of SDV & smos-box know this value – consistent with L2 SM May need to adjust MATLAB scripts?

9. www.argans.co.uk SMOS L2 Ocean Salinity – status, 08/07/2009 Other problems fixed Cleaned up and corrected GUI breakpoint list Corrected tests for missing ECMWF data: – Sea_Ice_Cover needed by all config – Drag_Coefficient_With_Waves needed by roughness model 1 – Minor changes to AUX_CNFL2OS for DPGS removed L2_Creator added List_of_Hosts: new definition of HW_Identifier

10. www.argans.co.uk SMOS L2 Ocean Salinity – status, 08/07/2009 Other problems fixed Now all %: – Tg_gal_noise_max, Tg_gal_noise_pol_max, Tg_moonglint_max, Tg_sun_glint_max Flag Tg_sunglint_max,Tg_suspect_ice, Tg_lat_ice_Acard can now be modified in GUI Fg_ctrl_ECMWF = 0 means missing ECMWF data (corrected in ATBD)

11. www.argans.co.uk SMOS L2 Ocean Salinity – status, 08/07/2009 Other problems fixed Tg_sunglint_max%, Tg_moonglint_max%, Tg_gal_noise_max% - all 10% (in TGRD) Dg_Suspect_ice, Dg_galactic_Noise_Error, Dg_galactic_Noise_Pol, Dg_quality_Acard now written to UDP
