Paper Abstract

A lidar system for determination of vertical profiles of the aerosol extinction coefficient, operating with 355 nm and 532 nm laser wavelengths, is presented. Lidar measurements will be performed within the European collaboration named EARLINET-ASOS and data will be used as a part of the assessment of a method for prediction of the observation range of optical systems in the atmosphere, based on meteorological weather forecast models. The lidar system has been extended with a detector channel for elastic scattering at 532 nm and Raman scattering from N2 at 387 and 607 nm to enable determination of the aerosol extinction coefficient. Extinction coefficients and backscatter coefficients will later be compared to corresponding values received from meteorological predictions of atmospheric aerosols. The aerosols prediction will be calculated using weather forecast model (HIRLAM) together with a forward dispersion model in the chemical transport model MATCH. Atmospheric scattering calculations (Mie-calculations) will give extinction and backscatter coefficients so comparison can be with lidar measurements. The design of the lidar system and the first measurements will be presented.
