Paper Abstract

Three improved methods for correction ofthe aerosol optical thickness of the atmosphere are presented. The first method provides for obtaining the absolute values AOT or their relative spectral behavior in some wavelength ranges. The method enables to find and exclude systematic errors in AOT. The second method requires knowing the absolute value of AOT in the only wavelength range. The values AOT in other wavelength ranges are corrected. The third method is used at complete absence of the absolute values or the relative spectral behavior of AOT. It is called "the method of zero point". This method suggested equating with zero the minimum value of AOT in one of the wavelength ranges. In contrast to the methods suggested earlier, where the orthogonal rms regression was used for determining the relation between different ranges of the spectrum of AOT, new methods use the generalized formula of linear regression obtained taking into account the random errors in the attracted data.
