Aerosol Backscatter Measurements At 10 µm Using A CO2 Laser Anemometer Developed For Aircraft Certification

An in-flight laser anemometer developed by CROUZET for true air speed measurements and aircraft certification has been used to provide new informations about the aerosols backscatter coefficient at 10 pm in the lower atmosphere. The CO2 laser anemometer has been flown on a Mirage III up to an altitude of 13 km. In 1987, 10 flights over the central part of France were taken from May through October during various meteorological conditions.
