Shanwei's air quality benefits from its exceptional Guangdong eastern coastal position on the South China Sea, with consistent South China Sea trade winds providing reliable maritime ventilation. Vehicle traffic on surrounding expressways and the nuclear energy, fisheries, and manufacturing corridor contribute local sources, while the nuclear plants' essentially zero direct combustion emissions and the outstanding coastal exposure maintain Shanwei among Guangdong's more moderately ventilated eastern coastal cities.

When is air pollution at its worst in Shanwei?
Air quality in Shanwei tends to be worse when traffic emissions together with manufacturing activity build up and onshore breezes fall calm. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Shanwei 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.
