Maoming's air quality reflects the Guangdong coastal plain's Maonan River valley position, with vehicle traffic on surrounding expressways and the petrochemical refinery — one of China's largest — and palm oil processing operations generating elevated industrial SO₂ and PM2.5. Consistent South China Sea trade winds provide maritime ventilation, while the petrochemical refinery's industrial scale represents Maoming's most distinctive local air quality contribution and the coastal ventilation generally manages emissions on most wind days throughout the year.

When is air pollution at its worst in Maoming?
Maoming usually sees its poorest air quality when road traffic as well as heavy industrial and chemical processing coincide with periods when dry spells bring strong winds. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Maoming 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.
