New challenges in submillimeter wave astronomy require instruments with a combination of high sensitivity andangular resolution, wide field of view and multiwave (multicolor)spectral range. New large single mm/submm telescopes are in high demand, as well as their inclusion in the global Event Horizon Telescope (EHT) VLBI network. At the same time, there are no large mm/submm telescopes in Asia at allwhile appropriate sites exist and their appearance in Asia or Eurasia is long overdue.Kinetic inductance detectors (KID) are ideal for large-format array implementation, which will be necessary for future telescope development. Concept of multicolor subTHzKID-array MUSICAM demo camera and its instrumental testing is given. It allows us to perform some necessary steps toward the creation of the Eurasian SubMillimeter Telescopes (ESMT), which concept and scientific tasks are presented as well.

“…The problems of measuring and monitoring humidity in the atmosphere at various altitudes are of special interest. The effects of the absorption of microwaves in water vapor are extremely important for radioastronomic measurements and, moreover, determine the astronomical climates and locations of the sites chosen for the installation of radioastronomic instruments [ 16 , 17 ]. Water vapor and hydrometeors considerably affect the kinetics of electrons in the electric field and, consequently, determine the evolution and properties of electric discharge phenomena in the atmosphere [ 18 , 19 , 20 , 21 , 22 , 23 , 24 ].…”

A high-sensitivity sensor for measuring moisture content in the air or air humidity under low pressure was designed on the basis of a half-wave coaxial microwave cavity. The method of measuring small variations in the signal phase at a cavity excitation frequency of 1.63 GHz was applied to detect low densities of water vapor. It allows the detection of variations in dielectric air permittivity in the seventh decimal place. A prototype of the sensor was tested in a vacuum chamber. It was calibrated by comparing the test results with the readings of a commercial pressure gauge and using the independent method of measuring the moisture content in rarefied air on the basis of the absorption of millimeter waves in the local line of water vapor at 183 GHz. The developed sensor can be used in laboratory experiments and full-scale geophysical research in the atmosphere onboard various aircrafts.

“…Due to the high interest to the appearance of submm telescopes in Eurasia, it is relevant to study the astroclimate of their placements [4][5][6][7][8]. This paper continues the search for locations of the submm telescopes in Eurasia, started in [6], using the data from the European Center for Medium-Range Weather Forecast ReAnalysis (ERA5) and the geodetic stations of the Global Navigation Satellite Systems (GNSS).…”

Using the ECMWF Reanalysis v5 (ERA5) and the GNSS method as well as meteorological and observational data, the statistics of the PWV, TCC, SD, and other astroclimate indicators were obtained for a number of possible ESMT locations in the Russian Federation. These sites are compared with the Ali observatory in Tibet and the BTA location area. The first results of the GNSS PWV measurements on Mt. Kurapdag convincingly confirm the choice made earlier using the ERA5 data.
