Abstract

The CNES/DLR MERLIN satellite mission aims at measuring methane dry-air mixing ratio column (XCH₄) and thus improving surface flux estimates. In order to get a 1% precision on XCH₄ measurements, MERLIN signal processing assumes an averaging of data over 50 km. The induced biases due to the non-linear IPDA lidar equation are not compliant with accuracy requirements. This paper analyzes averaging biases issues and suggests correction algorithms tested on realistic simulated scenes.
