1. SMOS QWG-11, ESRIN 4-5 July 2013 L2OS v600 status and evolution 1 The SMOS L2 OS Team

2. SMOS QWG-11, ESRIN 4-5 July 2013 Delivered end 2012, not yet ingested in DPGS v600 changes wrt v550 presented in detail at QWG-10 v610 prepared (but not yet verified with L1 v600) –OTT post-processor –TEC from Stokes 3 –Multi-threading –New UDP and DAP contents Impact of sky map error still under analysis (not only in L1 but also in galactic scattering model) 2 L2OS v6.00

3. www.argans.co.uk SMOS L2 Ocean Salinity FAT 18/19 December 2012 – redelivery 25/1/2013 with updated schema Significant changes from v550 new RFI snapshot level detection, improved RFI outlier detection new galactic noise model LUTs (ascending/descending) filters & flags moved from code to configuration ADFs improved Acard filtering near ice changes to UDP & DAP formats removed Fg_ctrl_gal_noise from Fg_ctrl_poor_geophysical bug fixes to iterative scheme, TB_42.5, galactic noise flagging L2OS v600 status

4. SMOS QWG-11, ESRIN 4-5 July 2013 Tuning v610 modifications Improving RFI detection Possible change in OTT strategy after analysing L1 improvements impact (Sun, calibration, new galactic map, …) Possible modifications in roughness correction (two-step retrieval, using polarimetric information, …) Improved inversion technique Improved dielectric constant model Possible use of fusion at L1 4 Future improvements
