Uma ferramenta para visualização da qualidade do ar com dados de monitoramento de poluentes atmosféricos

Abstract

Climate change and its impacts on ecosystems, human health, and well-being remain a key topic of discussion within the international community, along with the necessary solutions for monitoring and mitigating these effects. To this end, numerous projects and guidelines have been published on the implementation and operation of air quality monitoring networks, which provide data on atmospheric pollutant levels in cities and regions. However, to transform this data into meaningful information and knowledge, it must be presented intuitively, ensuring easy comprehension by the target audience. In this context, this study proposes the development of a web-based tool for visualizing air quality monitoring data through interactive maps. The system is implemented using leaflet.js and written in JavaScript, processing pollutant measurement data from air quality monitoring systems to calculate the Air Quality Index (AQI). As a result, the tool features a dynamically rendered mapping system based on user-selected filters, displaying AQI information across the administrative subdivisions of the analyzed city. This facilitates a clearer understanding of the collected data and can serve as a public information resource for citizens to monitor environmental conditions or as a tool for studying the trends and behavior of pollutant levels.
