Assessing the possibilities of sensing CH4 and CO2 greenhouse gases above the underlying surface with satellite-based IPDA lidar

Abstract

The IPDA method is used to analyze the possible uncertainties of CH4 and CO2 measurements in the troposphere in the presence of clouds. The choice of wavelengths is substantiated. A software system written for simulating the radiative transfer in satellite sensing is briefly described. It is shown that multiple scattering under cloudy conditions can influence the power of the received signal at a single wavelength; at the same time, the use of a differential scheme mitigates this effect for closely lying wavelengths. We calculate the uncertainties versus underlying surface altitudes and the presence of clouds.
