Project: Will Air Quality Have an Exceedance Today? 24-Hour Ozone Forecasting on the Highveld
Team: n-ary
Students: Kamogelo Moukangwe and Rivoningo Mageza
Partner: Geography, Geoinformatics and Meteorology Department, University of Pretoria

A machine learning system predicts hourly ozone concentrations up to 24 hours ahead using data from 36 SAAQIS stations and Open-Meteo weather data. Random Forest (R²=0.781, RMSE=5.94 ppb) and XGBoost (R²=0.776, trained 20× faster) provide the best results. An interactive Streamlit app delivers 24-hour forecasts with visual alerts when ozone exceeds 61 ppb and optional daily subscriptions.
