Abstract
Session4 (Applications of optical turbulence observations and custom forecasting in telescope astronomy.)
Title'Seeing estimation from 200 mb wind speed in the ELT campagne '
AbstractAtmospheric turbulence caused by heat from ground rising through the atmosphere, and wind stirring the atmosphere up, affects observational astronomy through the well known parameter “seeing”. Numerous layers of strong winds in the atmosphere cause a lot of turbulences degrading astronomic images.
Vernin et al 1996 have already reported good correlations between wind speed at 200 mb and measured seeing at Hawaï and La Silla. In this work, first of all, we will compare the wind speed at 200 mb and the seeing measured at an astronomical observatory located at the Atlas mountains of Morocco at 2760 m of altitude. Then, as Morocco is part of the ELT project prospect, we will try to scan all the area of Morocco and the Canary Islands in order to estimate the seeing values starting from wind speed data taken from the National Oceanographic and Atmospheric Administration.
