Rayleigh-Mie Doppler wind lidar for atmospheric measurements. II. Mie scattering effect, theory, and calibration.

A theoretical and experimental study is conducted for the direct-detection Doppler Lidar developed by the Service d'Aéronomie du Centre National de la Recherche Scientifique. Thanks to a specific design, the double-edge technique that applies primarily to Rayleigh scattering can also be employed in presence of aerosols backscatter. We focus on a careful estimate of the particle-induced error on the wind measurements.

Rayleigh-Mie Doppler wind lidar for atmospheric measurements. I. Instrumental setup, validation, and first climatological results.

Since 1989 Service d'Aéronomie du Centre National de la Recherche Scientifique has used an incoherent Doppler lidar technique for wind measurements in the atmosphere. A new-generation Rayleigh-Mie Doppler lidar has been designed and is currently operated at the Observatoire de Haute Provence (France). We give a detailed description of this instrument and highlight two important upgrades leading to quasi-simultaneous and absolute measurements of the wind from approximately 8 to 50 km altitude.
