  2. Use only alias-free brightnesstemperatures, excluding border pixels within 0.044 dircosineunits of borderBrightnesstemperatures and retrieved SSS are projected onto earthdwelllines and averaged as usual.A single May 2011 OTT isapplied to both May 2011 and November 2012.Additionally, for eachmap of (Tx+Ty)/2 bias for the two versions v504 and v620, the medianbiasissubtractedfrom the map.For the SSS biasmaps and for the v620-v504 differencemaps, no median offset isremoved.

  16. FIRST STOKES PARAMETER DIVIDED BY TWO (Tx+Ty)2 Nov 2012; Descending passes; V620

  17. FIRST STOKES PARAMETER DIVIDED BY TWO (Tx+Ty)2 Nov 2012; Descending-Ascending passes; V504

  18. FIRST STOKES PARAMETER DIVIDED BY TWO (Tx+Ty)2 Nov 2012; Descending-Ascending passes; V620

  21. RETRIEVED SALINITY Nov 2012; Descending-Ascending passes; V504

  22. RETRIEVED SALINITY Nov 2012; Descending-Ascending passes; V620

  23. V620-V504 DIFFERENCES

  24. RETRIEVED SALINITY May 2011; Ascending passes; V620-V504

  25. BIAS IN (Tx+Ty)/2 May 2011; Ascending passes; V620-V504

  26. RETRIEVED SALINITY Nov 2012; Descending passes; V620-V504

  27. BIAS IN (Tx+Ty)/2 Nov 2012; Descending passes; V620-V504

  28. THIRD STOKES PARAMETER IN INSTRUMENT BASIS

  29. BIAS IN THIRD STOKES Nov 2012; Descending passes; V504

  30. BIAS IN THIRD STOKES Nov 2012; Descending passes; V620

  31. BIAS IN FOURTH STOKES Nov 2012; Descending passes; V504

  32. BIAS IN FOURTH STOKES Nov 2012; Descending passes; V620

  33. BOTTOM LINE:Land contamination stillpresent in V620.Shadowingseemsreduced for third Stokes in V620, but not for fourth Stokes.But the Fourth Stokes does look better over the open ocean in V620 than in V504.
