Integral-equation method for interpreting laser-sounding data on atmospheric gas components using differential absorption.

Data on laser sounding of an atmospheric humidity field are interpreted by using the differential-absorption method. A regularizing algorithm for restoring the accuracy of the water-vapor profile by resolving the errors of optical measurements and fluctuations of the aerosol backscattering coefficient is suggested. The efficiency of the inversion method is illustrated, using a numerical experiment and examples of restitution of the humidity profiles based on data of laser sounding up to 8-km altitudes.
