Studying the astroclimate at Baikal Astrophysical Observatory by optical methods

Atmospheric and Oceanic Optics, 2014
A technique is proposed for measuring astroclimate characteristics of the Baikal Astrophysical Observatory (BAO) by analysis of the quality of images obtained at a full Sun phase telescope. To estimate the image quality, a modified statistical information “optimal window” algorithm is used.

Millimeter-wave astroclimate investigations on badary observatory near Baikal lake

2017 XXXIInd General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2017
This paper deals with results of long-term astroclimate investigations in millimeter-wave band in the Badary observatory near Baikal lake. The optical depths for the 3-millimeter and 2-millimeter-band windows have been determined with the atmospheric dip method.

The Results of Observing the Astroclimate on the Crimean Peninsula in the Shortwave Part of the Millimeter Wavelength Range

Astrophysical Bulletin, 2018
We present the results of a study of the astroclimate on the Crimean Peninsula in the vicinity of the UNN Kara-Dag radioastronomical station (located at a height of 105 m above sea level). The measurements were taken in semi-automatic mode every 2 minutes from July 22 to September 21, 2017.

Analysis of the Results of Astroclimate Research at the Kara-Dag Radioastronomical Station in Crimea and the Possibilities for Reducing the Influence of the Atmosphere on Millimeter-Band Radioastronomical Observations

Journal of Experimental and Theoretical Physics, 2019
The results of astroclimate research at the Kara-Dag radioastronomical station (Crimea) from July 22 to September 21, 2017, are presented. The algorithms for processing the data obtained by the atmospheric profile method are analyzed. The broad bands of the MIAP-2 receivers are shown to lead to a non-cosecant dependence of the antenna temperatures on ...
