GHRSST XVII Science Team Meeting: 6th - 10th June 2016 in Washington, DC, USA
OUTLINE:
1. Brief review of the presentation of the last GHRSST
2. The problem: a curious positive bias values were observed on SST retrieval of until 4 K.
3. Analysis of turbulent fluxes
4. An attempt to solve an unexpected positive SST bias by using optimal estimator (OE)
5. Conclusions
