Av. Vasil'Ev et al., Analysis of the information content of measurements of outgoing reflected and scattered solar radiation in the 240-700 nm spectral band, EARTH OBS R, 16(2), 2000, pp. 257-268
Spectral covariance matrices for outgoing radiation in the 240-700 nm spect
ral band (921 channels, spectral resolution 0.5 nm) are calculated. The num
ber of independent informative components of radiation is determined for a
complex inverse problem (surface albedo, O-3 and NO2 content, atmospheric d
ensity, optical characteristics of aerosols) and for individual inverse pro
blems for various conditions of satellite experiment. It is shown that the
outgoing radiation contains 8-11 independent informative components for the
vertical ozone profile, 5-8 for the profile of the atmospheric density, 6-
12 for profiles of the optical characteristics of aerosols and 1-3 for the
NO2 profile.
