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.
Geographic information technologies and software for quick assessment of air pollution are considered. The developed tools are the basis of the air monitoring system of Krasnoyarsk created at the Federal Scientific Center of the Siberian Branch of the Russian Academy of Sciences. The results of measurements of particulate matter concentrations at air monitoring stations in different areas of the city for the winter period 2019 - 2020 are presented. The results are compared with the data of the regional state departmental environmental monitoring system of the Ministry of ecology of the Krasnoyarsk territory.
