Jianshe in China reflects the flat North China Plain's urban manufacturing corridor position, with vehicle traffic and industrial operations contributing local sources. Winter residential coal heating generates elevated PM2.5 under inversions and the regional industrial background elevates winter readings throughout the year.

When is air pollution at its worst in Jianshe?
Air quality in Jianshe tends to be worse when vehicle traffic along with manufacturing and food processing build up and dry, windy weather picks up. These wind events can carry dust in from the surrounding arid landscape. Fuel burned for winter heating adds an extra layer of particulates on top of other sources.
Are air quality levels in Jianshe 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
