2. SMOS L2 Ocean Salinity www.argans.co.uk 2 Priorities for 2015 investigations, L2OSv7XX and beyond. Major priorities for 2015 1)Develop and implement an Empirical Correction of L1c Tbs for minimizing Land Sea Contamination at L2 2) Refine the filtering of L1 contaminated data (RFI, sun, sunglint, etc..) 3)Provide improved roughness correction methods: -new GMF (higher winds) -sea state effects -two (multiple)-step inversions Second order priorities: 4) Refine OTT strategy 5) Refine glint models (galactic and sun) 6) Improved QC control in inversion 7) Test new implementation of retrieval methods (two-step, monte-carlo) 8) Production of a SMOS TEC

6. SMOS L2 Ocean Salinity www.argans.co.uk Priorities & status for 2015 investigations (from DIP) 6 Mixed-scene correction: empirical Correction&/or filtering Method for the Land- Sea Contamination (priority 1, lead NR) implemented in L2OS prototype: 2G ADF, +30 seconds to read, +1G RAM JT will present status Filtering: refined L1 contaminated data filtering (RFI Sun, others...) (priority 1, lead JLV) analysis of reprocessing products will start soon… Roughness: improvement of the nonlinear roughness corrections (priority 1, lead NR) LOCEAN working on model 1 Status of model 2 (Ifremer) & model 3 (BEC) TBD Improvement in Glint Models (priority 1, lead JT) Will be done after mixed-scene correction TBD TEC follow-up and product definition (priority 2, lead JLV) on-going, no presentation yet

7. SMOS L2 Ocean Salinity www.argans.co.uk Deliveries for 2015 7 Mid-2015 (to July): Progress Report L2OS reprocessing report Land-sea contamination bread-board & TN; Performance Assessment TN/TDS definition; prototype processor implementing land-sea contamination algorithm using ADFs from JT updated roughness models & TGRD from ESL –everybody TN on L1 data filtering based on new reprocessing End-2015 (November/December): Progress Report Land-sea contamination: TDS results & ESL analysis (PPSR); new version of L2OS processor with all documentation and ADFs for DPGS & reprocessing deployment, with all approved improvements (expected to be land-sea, roughness & galactic glint), following FAT updated AUX_GAL2OS & TGRD & TDS & PPSR TEC product definition TN
