In Chengxiang, vehicle traffic, manufacturing and food processing, as well as crop farming are the main local sources, with conditions worsening when maritime winds die down. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. This coastal advantage is less pronounced during still, high-pressure weather.

Are air quality levels in Chengxiang based on measurements or forecasts?

It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
