LEANDRE II
Lidar pour l’Etude des interactions Ae´rosols Nuages Dynamique Rayonnement et du cycle de l’Eau

The LEANDRE II is an airborne lidar system developed at the Service d’Ae´ronomie du Centre National de la Recherche Scientifique (CNRS) in Paris. It uses the differential absorption lidar technique to provide profile measurements of water vapor mixing ratio. LEANDRE II operates in a double-pulse, double-wavelength mode in the 727-770 nm spectral range. It has a vertical resolution of 300 m and a horizontal resolution of 800 m. LEANDRE II has a double-pulse temporal separation of 50 microseconds and a repetition rate of 10 Hz.
