Abstract
A linear relationship between the variations in radiance measured in the visible and near infrared by satellites and variations of aerosol-extinction profile has been derived, hence reducing the problem to that of solving a Fredholm integral equation of the first kind. The retrieved profiles, by the linear constrained-inversion method, have proved to be accurate in the lower atmosphere, even if simultaneous changes are taking place in the stratosphere. Variations in the stratosphere, however, are retrieved with a lesser degree of accuracy and only as long as no variations occur in the tropospheric haze.
