  1. UPDATE ON SMOS LONG-TERM BIASES OVER THE OCEAN AND ROUGH SURFACE SCATTERING OF CELESTIAL SKY NOISE Joe Tenerelli SMOS L2OS Progress Meeting Arles, France, September 26, 2011

  2. SMOS PASSES USED IN THIS ANALYSIS

  3. DRIFT IN 2010 ONLY

  4. NO LOSS MODEL

  5. ONE-SLOPE LOSS MODEL

  6. TWO-SLOPE LOSS MODEL

  7. EXTENSION THROUGH JUNE 2011

  8. NO LOSS MODEL

  9. ONE-SLOPE LOSS MODEL Notice the significantdesc-ascbiasnowappearingwithboth one and twoslopelossmodelsbetweenNov 2010 and April 2011. It is of opposite sign to thatbetween Sep and Dec 2010 observedwith no loss model. It appearsthat the loss correction istoostrong in thisperiod.

  10. TWO-SLOPE LOSS MODEL The two-slope model seems to degradedesc-ascbias relative to the one-slope model.

  11. ONE-SLOPE LOSS MODEL: IMPACT OF GALACTIC REFLECTION MODEL It turns out that, for the metricsusedhere, the impact of the formulation of galactic noise scatteringat the surface on desc-ascbiasisquitesmalleven for descending passes in September. Kirchhoff scatteringmodel for galactic noise

  12. ONE-SLOPE LOSS MODEL: IMPACT OF GALACTIC REFLECTION MODEL It turns out that, for the metricsusedhere, the impact of the formulation of galactic noise scatteringat the surface on desc-ascbiasisquitesmalleven for descending passes in September. Flat surface reflection model for galactic noise

  13. DRIFT METRICS

  14. LONG TERM DRIFT JAN-DEC 2010

  15. LONG TERM DRIFT JUN-DEC 2010

  16. LONG TERM DRIFT JUNE 2010 – JUNE 2011 Considering the June 2010 to June 2011 period, thereisverylittle net drift in the AF and EAF FoVs In the ascending passes.

  17. SHORT TERM DRIFT IN 2010 AND 2011 The two-slope model seems to degradedesc-ascbias relative to the one-slope model. Two-slopedegradesdesc-ascconsistency
