The methanol molecules in atmosphere remote sensing by the Raman spectrum

The Raman back scattering lidar equation for the methanol molecules numerical solution results at the methanol molecules remote sensing in the atmosphere with concentrations in the range 10$^{12}$–10$^{18}$ cm$^{-3}$ at the range distances up to 1000 meters in the synchronous photon counting mode are presented. It is shown that during the measurement time of 1 s with such a Raman lidar at the 405 nm laser wavelength, it is possible to probe the methanol molecules with a concentration level of about 10$^{16}$ cm$^{-3}$ at distances up to 600 m.
