Astroclimate of the Terskol Observatory

Adaptive Optics Systems IX
Astroclimatic conditions characterize the quality of an astronomical site. The Terskol Observatory was founded over 42 years ago in 1980. The astronomical site (coordinates 43◦16′29′′ N,42◦30′03′′ E) is located about 10km from Mt.

Study of the astroclimate at the Baikal Astrophysical Observatory

Modern astronomy: from the Early Universe to exoplanets and black holes
The atmospheric conditions are crucial for an astronomical observatory. Earth's atmosphere limits image quality in ground-based optical telescopes. The knowledge of the atmospheric turbulence vertical distribution above an astronomical site is significant for the design and operation of adaptive optics systems as well as for scheduling the observing ...
