The pollutants emergency emission in the atmosphere sensing by the space platform lidar is the new perspective in the global environmental monitoring. The Raman lidar potential possibilities theoretical estimation for the alkane hydrocarbon molecules emission in the near-Earth atmospheric layer at the concentration level of the limit admitted level and above detection from the space orbit presents this paper task. These Raman lidar equation computer simulations results show that optimal lidar variant for the given molecules concentration level, Raman pulse energy is equal to 1 photon, the methane molecules sensing from the 600 km height and lower is the laser radiation wavelength λ0 = 532 nm that the recording time for this wavelength and height range 100–600 km will change from 11 ms up to 385 ms.
