What was the purpose of LOSAC?

L-band Ocean Salinity Airborne Campaign (LOSAC) is a part of the preparation for ESA's SMOS mission, and the overall interest is to understand the nature of the wind driven signatures in order to evaluate, if corrections are necessary prior to salinity estimations based on the radiometer signals.

What was the outcome of LOSAC?

The LOSAC campaign was planned to identify eventual azimuth dependence over a full circle signature, carried out over the ocean. This has been done in six flights, providing six different wind conditions. At first sight all data show large peak-to-peak variations, typically in the order of many Kelvin. From a single circle, the identification of polarimetric signatures in the order of 100 mK is hence difficult or impossible.
