Abstract

New algorithms are developed to improve the methodology of the ozone profile extraction from the signals measured by an ultraviolet DIAL system in a turbid troposphere. A routine procedure is developed to estimate the likely boundaries of the uncertainty in the retrieved ozone concentration profile caused both by the errors in the measured signals and by an uncertainty in the atmospheric characteristics used for the ozone concentration correction (specifically, by uncertainties in the assumed aerosol backscatter-to-extinction ratio and spectral dependence of the aerosol extinction and backscattering). The algorithms are integrated into a computer program, and a preliminary verification of the new technique for the ozone concentration derivation is made with one and two pairs of the signals, measured at the on and off wavelengths of the DIAL system.
