Priorities for 2015 investigations, L2OSv7XX and beyond.

Major priorities for 2015

1) Develop and implement an Empirical Correction of L1c Tbs for minimizing Land Sea Contamination at L2

2) Refine the filtering of L1 contaminated data (RFI, sun, sunglint, etc..)

3) Provide improved roughness correction methods:-new GMF (higher winds)-sea state effects-two (multiple)-step inversions

Second order priorities:

4) Refine OTT strategy5) Refine glint models (galactic and sun)6) Improved QC control in inversion7) Test new implementation of retrieval methods (two-step, monte-carlo)8) Production of a SMOS TEC
