COMMENTS:
Participation to the WIND ( CNRS / DLR Airborne Doppler HDL) development.
Presently in development:
§ with Olivier Le Rille (PhD student): EMIL (Experimental Mid-Infrared Lidar) a 2µm- HDL (10 mJ / 10 Hz / 10 cm) for wind and backscatter measurements in the PBL (150 m and 3 s resolution).
with Anne Garnier and Jacques Porteneuve: a Mach-Zehnder interferometer for the DDD wind lidar located at the Observatoire de Haute Provence.
