Chaohucun in China reflects the flat Anhui Chao Lake basin position, with vehicle traffic and light manufacturing and agricultural operations contributing local sources. The Chao Lake provides limited natural ventilation, while winter anticyclonic inversions concentrate emissions and the area generally maintains moderate Anhui plateau corridor readings throughout most of the year.

When is air pollution at its worst in Chaohucun?
The biggest local contributors to pollution in Chaohucun are vehicle traffic, light manufacturing, and crop farming, particularly once calm, stagnant conditions settle in the surrounding valley. Topographic enclosure in the valley lets pollution accumulate rather than clear out. The effect is strongest during the colder months, when inversions set in most often.
Are air quality levels in Chaohucun 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.
