    Information System for Air Quality Assessment and Data Processing: Design and Implementation
    (CEUR-WS Team, Aachen, Germany, 2024) Hnatushenko, Volodymyr V.; Bulana, Tetiana; Gomilko, Igor; Molodets, Bohdan; Boldyriev, Daniil
    ENG: In recent years, the issue of air quality has become increasingly critical. This article presents a hardware and software-based solution for collecting and processing data from ground stations monitoring air quality. The system is designed to collect real-time data from monitoring stations, store the data in a central database, perform data processing, and detect anomalies. Additionally, the system offers data visualization through maps and tables. The developed solution consists of three core components: a web server, a web application, and ground stations. A key feature of the software is its ability to handle real-time data aggregation and fill data gaps using custom-built aggregators. This is achieved through real-time data parsing, managed by Celery workers and queued via RabbitMQ. All data is stored in an SQL database, with PostgreSQL and Django frameworks facilitating database management and administration. Python scripts are used to process raw data into user-friendly formats such as AQI indices and graphical representations. The system is designed for seamless deployment across multiple remote servers, ensuring high flexibility and reliability for researchers. This software architecture enables scalable, conflict-free deployment, enhancing the efficiency and accuracy of air quality assessments.

    Information System of Air Quality Assessment Based of Ground Stations and Meteorological Data Monitoring
    (CEUR-WS Team, Aachen, Germany, 2023) Molodets, Bohdan; Hnatushenko, Volodymyr V.; Boldyriev, Daniil; Bulana, Tetiana
    ENG: Monitoring ground stations and collecting meteorological data are essential solutions for assessing air quality. A developed information system can aggregate and process the data obtained. The data is transformed into a unified format and returned through written application programming interfaces (APIs). Client interfaces were created for convenient display of the results. The project infrastructure is designed for easy deployment. The architectural solution for creating the system proposes a toolkit that optimizes system operation when performing complex tasks through asynchronous execution. The use of Docker during deployment provides additional capabilities. To calculate the distribution of emissions in Kryvyi Rih, the CALPUFF model was employed for data processing. The article describes the client part structure and interface description. It also displays the processed data, which is the result of applying a mathematical model to the meteorological and station data.

    Information System of Air Quality Assessment Using Data Interpolation from Ground Stations
    (CEUR-WS Team, Aachen, Germany, 2023) Molodets, Bohdan; Hnatushenko, Volodymyr V.; Boldyriev, Daniil; Bulana, Tetiana
    ENG: Monitoring ground stations is crucial for creating interactive maps that assist in assessing air quality. A developed information system can aggregate and process the data obtained, which is then transformed into a unified format and used as input data for interpolation methods that create raster imagery. After processing, the data is stored in Amazon Simple Storage Service or database and can be retrieved using application program interfaces (APIs). The proposed architectural solution for creating the system includes a toolkit that can work with different volumes of data with ease. Using Docker during deployment provides additional capabilities for creating a flexible and scalable system. Specific tools such as PostGis and Geospatial Data Abstraction Library (GDAL) simplify the processing of data. For instance, GDAL helps with the interpolation, cropping, and tiling of the air quality raster image. The article describes the structure of the client part and the interface in detail. By using the Mapbox Graphics Library system, the system can easily visualize big data as a vector layer, helping users recognize hazardous zones and find safe places.
