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)

• 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

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
