The subject of research was the vertical distribution of the concentration of solid particles during temperature inversions. The measurements were carried out using attachments mounted on the Unmanned Aerial Vehicle, including sensors for meteorological parameters and particulate matter. The flights were carried out during daylight hours in the absence of clouds at altitudes up to 500 m. It was found that in the presence of temperature inversion, the concentration of PM2.5 aerosol particles decreases with height and positively correlates with relative humidity. These patterns are violated when the atmosphere is polluted with the smoke of a city fire (the ignition area is about 12,500 m2).
The system of scientific-research monitoring of the state of the environment in Krasnoyarsk on the basis of the ICM SB RAS geoportal is discussed. Software has been developed for the subsystem for collecting data on photographic fixation of fogging processes over the Yenisei River. Data collection is carried out both from public city surveillance cameras and from a specialized network of IP video cameras. A visual monitoring system has been created that provides for the collection of images from public and private IP surveillance cameras, image processing, uploading to a structured file archive and organizing access through web applications and services. On the basis of the collected data, the problems of searching for patterns of formation of hovering fogs over the Yenisei channel are considered in order to study the effect of a non-freezing polynya on air quality in Krasnoyarsk.
This paper considers the state of the atmosphere in the city of Krasnoyarsk in terms of sustainable development based on an analysis of the data presented in the State Reports “On the State and Environmental Protection in the Krasnoyarsk Territory” for the period from 2007 to 2018. The volume of gross emissions, their structure and dynamics, as well as indices of air pollution are analyzed.
The state of atmosphere of Krasnoyarsk (Russia) in 2018-2019 is analyzed based on datasets provided by the Geoportal developed by the authors and connected to the regional system of ambient air monitoring. Statistical and dynamic behavior of PM2.5 concentration in the surface air is studied depending on the meteorological conditions and terrain relief of the city.
In this paper, we calculated the air quality index (AQI) for 2018 based on data from automated observation posts located in the city of Krasnoyarsk. The influence of individual components (pollutants) on the index value is analyzed.
