8 SMOS QWG-7, ESRIN 31-January – 1 February 2012 New 8 New SMOS OS L3 maps Optimally interpolated salinity maps generated at BEC from DPGS operational L2 products 10 days, 1 o x1 o, updated every 3 days

9 SMOS QWG-7, ESRIN 31-January – 1 February 2012 A new image processing technique allows to calculate singularity exponents with great accuracy. Singularity exponents are related to the flow dynamics: they trace streamlines. MW SST SMOS OS L4 products 9

10 SMOS QWG-7, ESRIN 31-January – 1 February 2012 A new image processing technique allows to calculate singularity exponents with great accuracy. Singularity exponents are related to the flow dynamics: they trace streamlines. Hence, singularity exponents are the same for any scalar. The analysis of the output of different numerical simulations confirm that SST and SSS have the same exponents (synergic effect) This implies that locally there is a linear relation between SSS and SST  SST can be used as template to remove noise SMOS L4 products 10

11 SMOS QWG-7, ESRIN 31-January – 1 February 2012 SSSSSTSSS SST images can hence be used to improve spatial correlations. Preliminary study shows improvement; ongoing work SMOS L4 products 11
