| The ability to accurately observe the Earth's carbon cycles from space gives scientists an important tool to analyze climate change. Current space-borne Integrated-Path Differential Absorption (IPDA) lidar concepts have the potential to meet this need. They are mainly based on the pulsed time-of-flight principle, in which two high energy pulses of different wavelengths interrogate the atmosphere for its transmission properties and are backscattered by the ground. We have previously proposed the Pseudo-Random Single Photon Counting (PESPC) IPDA lidar for this application. In this work we report through simulation the CO2 detection precision under the influence of various geophysical parameters, atmospheric pressure (altitude), as well as absorption cross-section of the CO2 at different wavelengths. It has been shown that the 1.5ppm threshold retrieval precision is attainable with 2W average power. | |
