Rongjiawan in China reflects the flat Hunan agricultural and light manufacturing corridor position, with vehicle traffic and agricultural processing contributing modest local sources. Winter coal heating generates seasonal PM2.5 elevation and the regional Hunan industrial background influences readings throughout most of the year.

When is air pollution at its worst in Rongjiawan?
Rongjiawan usually sees its poorest air quality when traffic emissions, light manufacturing, and agricultural burning coincide with periods when dry spells bring strong winds. Dust carried on these winds adds substantially to particulate levels. Coal and wood used for winter heating add substantially to particulate levels.
Are air quality levels in Rongjiawan 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.
