Abstract
A possible error of measurements in troposphere of CH4 and CO2 in the presence of clouds based on the IPDA methodology, the choice of wavelengths, and a brief description of the implemented software for the simulation of radiation transport for spaceborne lidar sounding is presented. It is shown that multiple scattering can influence the signal power, but differential absorption method eliminates this drawback. Errors in the calculations depending on the underlying surface heights and presence of clouds are given.
