| Abstract: | This paper considers the use of multifrequency radiometers to determine some emission properties of sea surface and its dependence on wind speed, atmospheric water vapor content, and liquid water content in clouds. The following aspects are analyzed: a) the sea state influence upon radiative characteristics of the "ocean-atmosphere" system, b) calibration of the data on range measurement, c) choice of spectral bands which provide optimum accuracy for determination of geophysical parameters with due regard to the spectral peculiarities of the functional relationships between the radiophysical and geophysical parameters and their uncertainties. Data are presented (with suitable illustrations) for an experiment to determine different hydrometeorological conditions and estimates of the accuracy of applied retrieval procedures. |
