The spectral technique for the problems of remote sensing through the clear and cloudy atmosphere

The purpose of the work is to derive the analytical formulas for spectral and angular distributions of upward radiation intensity, irradiated by point- or axisymmetrical sources, located at the Earth's surface or in the atmosphere, including the case of location inside the cloud layer. These formulas may be used in inversion techniques for the determination of the optical parameters of the atmosphere, clouds and objects by measuring the reflected or its own upward radiation in the visible and IR spectral range from an airplane or from space.
