The correlation between the radon influx into the atmosphere and the formation of ions has been studied from the data of observations at the Fonovaya Observatory of Institute of Atmospheric Optics, Siberian Branch, Russian Academy of Sciences. This correlation is shown to be stable in the period from October to January. In the other months, the cor...

Abstract—The effect of restrictions caused by the COVID-19 pandemic in Novosibirsk in spring 2020 on the composition of trace atmospheric gases and organic aerosol in the air of Novosibirsk Akademgorodok is investigated. The concentrations of aldehydes (formaldehyde, acetaldehyde, benzaldehyde, acrolein, and substituted aromatic aldehydes), the cor...

AbstractA technique for estimating the diameter of nanosize pores has been developed. It consists in filling a substance with liquid water, recording the absorption spectra of the substance with water, compiling a database of spectroscopic data which characterized the substance with different pore sizes, and retrieving the pore diameter of an arbit...

Abstract—The POKAZATEL line list is currently the most complete theoretical list of H2O monomer absorption lines. It contains H2O lines up to the dissociation energy ∼40 000 cm−1 (0.25 μm). The atmospheric transmission of ultraviolet (UV) radiation is simulated with the use of H2O lines from POKAZATEL. The broadening parameters of absorption lines ...

AbstractTheoretical aspects of nonlinear propagation of high-power ultrashort laser radiation in air in the filamentation mode with a transverse coronal-type intensity distribution formed by incoherent addition of several radiating subapertures arranged in a ring are considered. Using a numerical solution of the nonlinear Schrödinger equation avera...

AbstractRemote passive optical measurements of the state of waters in water basins studied from ships, airborne platforms, or satellites are most informative because they cover a large territory and are performed at a high frequency. At the same time, for correct estimation of the remotely obtained data some in situ measurements of the state of wat...

AbstractAn algorithm for estimating the size of the region in which cloudiness affects errors in retrieving the reflection coefficients of the Earth’s surface areas observed through breaks in the cloud field is proposed. The algorithm is based on statistical simulation of the process of radiation transfer through broken stochastic cloudiness by the...

AbstractWe present the results from statistical simulation of the albedo and diffuse transmission of the atmosphere in the visible wavelength region in the presence of overcast and broken cirrus clouds. The main numerical experiments were performed using the third version of the model proposed by B.A. Baum, P. Yang, A.J. Heymsfield et al. (a mixtur...

AbstractThe results are presented of experimental studies of a possibility of compensating for aberrations of the initial wavefront of an optical beam by the aperture sensing technique based on the atmospheric backscatter signal of radiation from an additional laser source at a different wavelength. The technique allows reducing the beam wavefront ...

AbstractThe dependence of the optical precipitation gage calibration results on the size of reference objects is analyzed. Ways to optimize the calibration procedure are suggested, including: reducing the number of calibration zones; use of calibration coefficients instead of correction parameters; additional calibration with balls 1 mm in diameter...
