Averaging Bias Correction for Future IPDA Lidar Mission MERLIN

Averaging Bias Correction for Future IPDA Lidar Mission MERLIN

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-linea...
