Simulations of roughness-salinity-temperature anomalies at S-L-bands

We report a novel class of ocean remote-sensing signatures associated with so-called “roughness-salinity-temperature anomalies” (RSTA). Oceanic RSTA can occur in restricted areas under the influence of joint variations of surface roughness, surface salinity, and temperature. The most probable environmental causes are interactions between thermohaline and wave processes. To provide an appropriate study, we develop numerical simulations of possible radiometric signals, images, and features. For this goal, we have used a composite multifactor hydrodynamic-electromagnetic model developed in our previous work. Examples of radiometric signatures related to RSTA will be demonstrated. We also point out possibilities for their observations using advanced passive microwave techniques. These results will be presented and explained.
