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...

New default values• -999• New versions of SDV & smos-box know this
value – consistent with L2 SM• May need to adjust MATLAB scripts?

Detecting sea-ice• SPH Sea_Ice is count of fg_sc_suspect_ice
• fg_sc_suspect_ice if (Dg_Suspect_ice)/nMeas > Tg_suspect_ice //default 50%
• Dg_Suspect_ice = count(fm_suspect_ice)
• fm_suspect_ice if (tb > (tbFwdModel + Tm_DT_ice ) //default 20°

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

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)

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
