Pure Cities: how temperature, wind and rain shape our air

This article explores the seasonal variations in air pollution and the influence of meteorological factors on pollutant concentrations, focusing on data from the “Pure Cities” project in Belgium. Analyzing pollutants like PM2.5, PM10, and NO2, the study highlights how temperature, humidity, wind speed, atmospheric pressure, and precipitation affect air quality throughout the year. Findings show that pollutant levels tend to rise during colder months due to increased residential heating and reduced dispersion. The article discusses the importance of addressing seasonal pollution through targeted strategies, such as enhancing public transport, promoting green spaces, and aligning regulations with WHO guidelines.
