| Summary: | 30% of the roughness at 6.6 GHz. The last change to the An increase in roughness is needed at frequencies above 16.6 atmospheric variables. These algorithms can then be used to back into the view path of the microwave sensor. This change brightness temperatures are used to obtain algorithms for changes yield an improved sea surface model that is within 2% emissivity functions. emissivity right. Several changes are made to Wilheit's sea for microwave frequencies. This model is used in a radiative GHz and a decrease below 16.6 GHz. The roughness is In 1979, Wilheit introduced a sea surface emissivity model increased to 132% of the Cox and Munk roughness at 37 GHz and increases- instead of being switched on at 7 m/s. These lowered the computed emissivity of the sea surface-, which is measurements- Therefore, it is important to get the surface model is in the treatment of sea foam. The foam effect is more representative of observations without sea foam. The now a smooth transition of increasing foam as the wind speed of the sea surface emissivity given by the Wentz sea surface reflections are now treated as if the radiation is reflected retrieve atmospheric variables from the microwave second change is made to the sea surface roughness parameter. surface emissivity model. The first change to the model is temperatures for various atmospheric conditions. The to the model's treatment of multiple reflections. Multiple transfer model (RTM) to obtain simulated brightness |
