Description
The requirements for excellent image quality of current large and future
very large telescopes demand a proper knowledge of atmospheric
turbulence. Thus several projects are already pursuing this aim. The
precise characterization of the turbulence above a particular site
requires long-term monitoring. In this sense, due to the lack of
long-term information on turbulence, high-altitude winds (in particular
winds at the 200-mbar pressure level, V200) have been
proposed (Sarazin & Tokovinin 2002,1 S&T02 hereafter)
as a parameter for estimating the total turbulence at a particular site,
because records of this parameter exist from several sources. This
choice is based on the idea that the greatest source for turbulence
generation is related to the highest peak in the vertical wind profile,
which is located at the 200-mbar pressure level globally. Moreover,
S&T02 found a good correlation between the average velocity of the
turbulence, V0, and V200 of the form:
V0= 0.4*V200 at the Cerro Pachón and
Paranal Observatories in Chile. A linear relationship between
V0 and V200 was also found in San Pedro
Mártir (Mexico) (Masciadri & Egner 2006,2
M&E06 hereafter). We study here the possible connection between
V0 and V200 at the Teide Observatory (Spain).
