Abstract
Air pollution is a significant environmental problem in urban areas, impacting millions of people's lives and leading to fatal and serious health effects. The World Health Organization (WHO) reports that almost 7 million people die from air pollution every year, and 90% of the world's population is breathing unhealthy air. While the Air Quality Index (AQI) helps represent air pollution levels in a standardised manner, most monitoring systems do not have any predictive ability for taking proactive decisions. This research introduces an intelligent air quality forecasting system with historical data and machine learning techniques to forecast the future air quality level. The system takes data from the major Indian cities from a multi-year period and incorporates certain pollutants (PM2.5, PM10, NO₂, SO₂, CO, O₃) and meteorological parameters. The data is preprocessed to deal with missing and inconsistent data. Various models such as regression models, ensemble models and deep learning models are tested. The results indicate that the advanced models are more accurate than the traditional ones, with XGBoost reaching an accuracy of more than 95% and the Bi-LSTM being able to capture temporal patterns well. The system provides 24-, 48-and 72-hour forecasts, which can be used for short term or medium-term planning. Particulate matter and meteorological factors are identified as prominent features in feature analysis. In general, it is scalable, and can help in making informed decisions for better air quality management and public health.
