High-Stability L-Band Radiometer Measurements of Saltwater.

L-band radiometer brightness temperature measurements of a saltwater pond were made as a function of salinity and temperature. A precision L-band radiometer with stability better than 0.1 K per day was used for these measurements. The L-band measurements are In good agreement with three dielectric constant models over a temperature range from 8°C to 32°C and a salinity range from 25-40 psu. Based on this experiment, these dielectric models will provide an excellent basis for the algorithm development and design of the future National Aeronautics and Space Administration Aquarius sateffite mission.
