Abstract
The emission theory for the sea surface by Stogryn has been reevaluated. Results agree with Stogryn\´s paper except for small nadir angles where the apparent temperature versus win speed behavior is in reverse of what was reported by Stogryn. By plotting the change in contributions by the sea surface emission and sky temperature scattered toward the radiometer as a function of nadir angle at two different wind speeds, it is found that the sky temperature effect is dominating at small nadir angles, while the change in surface emission becomes increasingly more important at larger nadir angles. It is also found that at nadir higher emission is associated with the polarization where
field is aligned along the upwind direction than the one along the crosswind direction.
