1 October 2009 Estimation of adaptive optics parameters from wind speed: results for the Teide Observatory
Author Affiliations +
The development of adaptive optics systems for projects related to large telescopes demands a proper knowledge of the atmospheric turbulence. Due to the lack of long-term information on optical turbulence, high-altitude winds (in particular winds at the 200-mbar pressure level) were adopted as a parameter for estimating the total turbulence at a particular site, since there are large wind databases spanning for several decades. On-site measurements of CN2(h) profiles (more than 20200 turbulence profiles) from G-SCIDAR observations and wind vertical profiles from balloons have been used tocalculate the seeing, the isoplanatic angle and the coherence time for the Teide Observatory (Canary Islands, Spain). The connection of these parameters to wind speeds at ground and 200-mbar pressure level have been studied and discussed.
