AB: Improved spatial and temporal coverage of atmospheric CO2 measurements is essential for a better understanding of the regional carbon cycle. Active remote sensing has the capability to make studies at various scales and could ultimately be operated from space. In this context, a 2-µm Heterodyne Doppler and Differential Absorption Lidar (HDIAL) has been developed and operated at IPSL/LMD to monitor both CO2 mixing ratio and velocities in the troposphere. In this paper, we will describe the instrument and field experiment results and comparison with in-situ sensors. In addition we will review the potential for future applications of CO2 lidar in regional-scale carbon cycle studies.
