Abstract

Ocean salinity measurements using the Passive Active L/S-band instrument flying on the NCAR C-130 aircraft were made in July 2002 near Monterey, CA. When the radiometer data were corrected for the SST using the Klein and Swift salinity model and surface roughness effects using the L-band scatterometer, the retrieved salinity measurements had an RMS difference of 0.2-0.3 psu when compared with the R/V Point Sur ship measured salinity data.
