Abstract
A differential absorption lidar (DIAL) has been developed at LMD to measure the variation of stable isotopic composition of CO2, δ 13C, in the atmosphere. The lidar uses a new 3-wavelengths single mode hybrid fiber/bulk pulsed laser at 2 µm and a coherent detection. We present the geophysical objectives of this work, the expected performances and the experimental set-up. Preliminary atmospheric results will be discussed at the conference.
