The Raman Lidar systems are powerful instruments for monitoring atmospheric parameters (backscatter coefficient, extinction coefficient, Lidar ratio, optical depth, water vapor) and processes (boundary-layer growth, aerosol and cloud layering, etc). The measurement principle of the LR-systems is based on elastic scattering by suspended aerosols (dust, water droplets, ice crystals, black carbon) and molecules of the atmosphere and elastic (Raman) scattering by water vapor (H₂O) and nitrogen (N₂) molecules. As a result the profiles of backscatter and extinction coefficient can be determined independently resulting in a dramatic reduction of associated uncertainties.

The LR-systems are available with different laser wavelengths (1064, 532 and 355 nm or any combination), detection wavelengths (1064, 532, 355 nm, Raman-H₂O, Raman-N₂ and polarization) and telescope aperture sizes. All systems are equipped with an industrial PC and dedicated software, including software modules for data acquisition, analysis and visualization. Eye-safe solutions are available on request.
