Зондирование молекул метанола в атмосфере по спектрам комбинационного рассеяния света

Abstract

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 1012 cm-3... 1018 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 1016 cm-3 at distances up to 600 m.
