Geophysical Contributions to Satellite Salinity Measurements[23-Feb-09] Among the important geophysical factors that need to be included in the retrieval of salinity from a sensor in space are emission from the atmosphere, Faraday rotation in Ionosphere, temperature and roughness (waves) of the ocean surface, and the presence of down-welling radiation from the celestial background that is reflected from the surface into the radiometer. The presence of rain and land within the antenna footprint also needs to be taken into account. Credit: NASA Aquarius.
