Abstract
The solution to the problem of light scattering by spherical particles is presented, adapted for the interpretation of lidar signals for applied problems. The solution was obtained for typical wavelengths used in laser sensing 0.355, 0.532, 0.905, 0.940, 1.064, 1.55, 2.15, and 10.6 mm within the Mie scattering theory for water and ice. The inherent high-frequency oscillations in the backscattering direction are smoothed out by means of a moving average, which allows one to construct fast and efficient algorithms for particle size distributions observed in the atmosphere.
