Astronomical Roentgen Telescope – X-ray Concentrator (ART-XC) is the hard instrument with grazing incidence imaging optics on board Spektr-Roentgen-Gamma (SRG) observatory. The SRG observatory flagship astrophysical mission of Russian Federal Space Program, which was successively launched into orbit around second Lagrangian point (L2) Earth-Sun system a Proton rocket from Baikonur cosmodrome 13 July 2019. ART-XC telescope will provide first ever true all-sky survey performed in 4–30 keV...
In this work, we compare the values of 15 convective indices obtained from radiosonde and microwave temperature water vapor profiles simultaneously measured over Nizhny Novgorod (56.2°N, 44°E) during 5 seasons 2014–2018. A good or moderate correlation (with coefficients ~0.7–0.85) is found for most indices. We assess thunderstorm prediction skills with a lead time 12 h each index. It revealed that effectiveness by much better than ones. Moreover, between certain index does not necessarily...
Ground-based passive measurements of downwelling atmospheric radiation at ~110.836 GHz allow extracting the spectra ozone self-radiation (rotational transition J = 61,5–60,6) coming from low stratosphere–mesosphere and retrieving vertical profiles concentration these altitudes. There is a notable (several hundred kHz) ambiguity in determination resonance frequency this important line. We carried out long-term ground-based microwave range using upgraded apparatus with high technical accuracy...
Ground-based microwave radiometers are increasingly used in operational meteorology and nowcasting. These instruments continuously measure the spectra of downwelling atmospheric radiation range 20–60 GHz for retrieval tropospheric temperature water vapor profiles. Spectroscopic uncertainty is an important part error budget, as it leads to systematic bias. In this study, we analyze difference between observed simulated obtained from more than four years radiosonde observations over Nizhny...
Features of the functional scheme and design millimeter wave radiometers with a new device - solid state modulator-calibrator using planar Schottky barrier diode microcircuit are presented.
The basic characteristic of terrestrial covers obtained by remote sounding is the brightness temperature. temperature a sum its self-radiation and atmospheric thermal radiation scattered on cover. In millimeter wavelength range, especially in short-wave part, temporal variations both components are comparable to natural contrasts various types covers. radio imagine terrain less stable, than it more long-wave spectral ranges. More stable cover emissivity ore albedo. two-frequency technique...
