Paper Abstract

Candidate sites of the future European Extremely Large Telescopes (E-ELT) need to be assessed and analytically compared in their observing characteristics. In the site selection process, meteorological, photometric and seeing qualities have to be studied and measured carefully. Aklim site in Morocco is one among four candidates in the ELT project. In this paper, we present meteorological studies of the Aklim site over eleven years. The meteorological parameters include wind speed and direction, relative humidity, air temperature, cloud cover and water vapour content. Most of these data are taken from the National Center for Environmental Prediction/National Center for Atmospheric Research NCEP/NCAR Reanalysis. The meteorological analysis covers the vertical profile as well as surface layer meteorology. Furthermore, in extensive literature, it has been demonstrated that the global circulation of atmospheric wind at 200 mb can be used as a criterion to establish the suitability for the development of adaptive optics techniques. By using the NOAA NCEP/NCAR reanalysis database, we analyse the monthly average wind velocity at 200 mb for eleven years period and compare with famous observatories.
