Abstract

The 1-meter Large Solar Vacuum Telescope (LSVT) is main instrument of the Baikal Astrophysical Observatory (BAO) of the Institute of Solar-Terrestrial Physics of Siberian Branch of Russian Academy of Sciences (ISTP SB RAS). The in-depth understanding of the Sun’s physics require optical observations of the Sun with higher and higher angular resolution. Therefore the development of adaptive optics is going for 1-meter LSVT. We present characterizations of free atmosphere from atmospheric ERA-Interim reanalysis data above BAO. The aim is estimation of the heights of turbulent layers above LSVT to select the heights of conjugation of deformable mirrors in the development of a multi-conjugated adaptive optics system. The profiles of inverse Richardson number (1/Ri), Brunt–Väisälä frequency, gradient of potential temperature and the total vertical wind shear are calculated for detection of heights in free atmosphere where most probably turbulence generation.
