Abstract:
A recent multi-sensor optical turbulence measurement campaign in the Haute-Provence region of France provided a unique comparison of optical turbulence sensors. Thermosondes from both the US and France were used. measuring temperature structure functions for 30 com, 95 cm, and 1 meter. In addition, turbulence was measured using a Generalized Scidar (GS) mounted on a 1.93 m diameter telescope at 1'Observatoire de Haute-Provence (OH). The GS measures optical turbulence strength and altitude from the scintillation of binary stars observed over periods from several minutes to several hours. The GS has 300 m vertical resolution from 25 km down to nearly the opt of the telescope. This paper describes the instruments and compares their performance. While the instruments did not yield identical results, agreement was reasonable. Jean VerninT, Max Azouit%, and Herve' Trinquet%
