We present a mobile lidar for measuring, in the ultraviolet (UV) region of the spectrum, the spatial distribution of ozone (O3) in the troposphere on the vertical and horizontal (slant) sensing paths, using the four-channel system of recording the return signals. The lidar operates, based on the lidar differential absorption and scattering method on the wavelength pair of 299 nm and 341 nm. We present a technical description of the lidar developed.

A possibility of monitoring greenhouse gases (CO2 and H2O) along horizontal paths in the troposphere with two-channel near-IR lidar system based on an absorption spectroscopy measurement technique is estimated. The main units and components of the IR lidar under development are described. A backscattered signal is simulated in the informative range of IR lidar for sensing target greenhouse gases.
