“…For the Sverdlovsk region, where the Beloyarsk NPP is located, strong variability in daily average aerosol characteristic values in the lower atmosphere layer is observed due to the combined influence of local sources of aerosol emissions and meteorological factors. The average concentrations of PM2.5 aerosols for the entire observation period are 10.3 μg/m 3 for the city of Yekaterinburg [6]. The obtained results are of interest in the study of the formation of the "respirable" fraction of aerosol particles, which almost completely settle in the lungs and bronchi and pose a serious threat to human health.…”

The article focuses on the study of the possibilities of a microwave radiometer for remote detection of increased radioactivity in the plume of gas-aerosol emissions from nuclear power plants caused by fast neutrons. This is a highly relevant issue due to the recent commissioning of new reactors using fast neutrons and the high number of accidents at nuclear facilities. The technical characteristics of the radiometric system are presented, and a quantitative analysis of radioactive emissions from nuclear power plants with fast neutrons is conducted. A slight decrease in the total amount of radioactive emissions is observed. The physical and chemical interactions between the released radionuclides and atmospheric components are also investigated. The maximum distances within line-of-sight at which gas-aerosol radioactive emissions can be detected in real-time mode in the frequency range of 1.4-1.8 GHz are determined.

“…Without any extended direct aerosol monitoring networks, one of the ways to obtain information about the aerosol content in the atmosphere is to build regression models linking direct ground-based measurements of aerosol concentration at one or more monitoring points, integral characteristics of remote sensing of the atmosphere (aerosol optical depth) and meteorological parameters [12][13][14]. With this approach, it is possible to estimate the spatial distribution of surface aerosol concentrations based on remote satellite sensing of the atmosphere in the studied region [15][16][17].…”

The present work aims to develop a regional Middle Urals Aerosol model (MUrA model) based on the joint analysis of long-term ground-based photometric measurements of the Aerosol Robotic NETwork (AERONET) and the results of lidar measurements of the CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation) satellite relying on information on the air trajectories at different altitudes calculated using the HYSPLIT (Hybrid Single Particle Lagrangian Integrated Trajectory model) software package. The MUrA model contains parameters of normalized volume size distributions (NVSDs) characterizing the tropospheric aerosol subtypes detected by the CALIPSO satellite. When comparing the MUrA model with the global CALIPSO Aerosol Model (CAMel), we found significant differences in NVSDs for elevated smoke and clean continental aerosol types. NVSDs for dust and polluted continental/smoke aerosol types in the global and regional models differ much less. The total volumes of aerosol particles along the atmospheric column reconstructed from satellite measurements of the attenuation coefficient at a wavelength of 532 nm based on the regional MUrA model and global CAMel are compared with the AERONET inversion data. The mean bias error for the regional model is 0.016 μm3/μm2, and 0.043 μm3/μm2 for the global model.
