Guankou in Hunan reflects the Hunan Yuanjiang River plain position, with vehicle traffic on surrounding roads and agricultural and manufacturing operations contributing local sources. Winter coal heating under flat inversions generates elevated PM2.5, while the regional Hunan industrial background influences readings and the flat terrain allows reasonable summer dispersal throughout most of the year.

When is air pollution at its worst in Guankou?
Air quality in Guankou tends to be worse when traffic on the surrounding roads, manufacturing and food processing, as well as crop farming build up and dry spells bring strong winds. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Residential heating through the colder months is a major seasonal source of particulates.
Are air quality levels in Guankou 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.
