The Air quality in urban areas<\/strong> application enhances air quality forecasts by integrating     satellite observations with advanced models like CHIMERE and machine learning to provide more accurate and  detailed predictions of aerosol pollution.<\/em><\/p>\n\n\n\n

Air quality forecast<\/strong><\/p>\n\n\n\n

Air quality monitoring and modelling application integrates Earth observation data with advanced simulation tools. The system combines the WRF meteorological model<\/a> and the CHIMERE chemistry-transport model<\/a> to analyse and forecast air pollution across Europe<\/strong> and in high detail over Marseille<\/strong>. (see map above)<\/p>\n\n\n\n

The modelling chain operates on two domains: a European scale (10\u201330 km) providing large-scale transport and boundary conditions, and a high-resolution domain over Marseille (1\u20133 km) capturing local emission dynamics from traffic, industry, maritime activities, and dust events.<\/p>\n\n\n\n

Using EDGAR emissions<\/a> for the European domain and AtmoSud<\/a> inventories for Marseille, and driven by CAMS global forecasts<\/a>, the application will deliver high-quality data and insights on air pollutant behaviour.<\/p>\n\n\n\n

This pilot application showcases how CLEAR-EO supports urban air quality management and evidence-based environmental policies through the integration of Earth observation, modelling, and data services.<\/p>\n\n\n\n

CLEAR-EO partners involved: SUEZ ARIA, UPEC, and SISTEMA<\/p>\n\n\n\n
