New SMOS OS L3 maps
• Optimally interpolated salinity maps generated at BEC from DPGS operational L2 products
• 10 days, 1ox1o, updated every 3 days
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.

• 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

• SST images can hence be used to improve spatial correlations.
• Preliminary study shows improvement; ongoing work
