Earth reflectivity

WebReflectivity is the capacity of an object to reflect solar radiation. It is described as a function of radiation wavelength and is determined by the physical composition of the object. The adjective “spectral” is frequently used in conjunction with reflectivity to indicate that reflectivity varies as a function of solar wavelength. WebApr 6, 2013 · Weather radars collect reflectivity data as a function of antenna azimuth and elevation, and from these so-called polar volume data, the rainfall products are derived. For the solar analyses, incidental Sun signals are detected automatically in the polar volume data, and the power, elevation, azimuth, and date/time stamp (for calculation of the ...
