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
