Zhoukou's air quality reflects the flat Huang-Huai Plain's central Henan agricultural position, with vehicle traffic on surrounding expressways and agricultural processing and residential heating contributing local sources. Winter residential coal and biomass burning generates elevated PM2.5 under frequent temperature inversions, while the flat terrain allows reasonable summer dispersal and the North China Plain's regional industrial background influences the broader corridor throughout the year.

When is air pollution at its worst in Zhoukou?
In Zhoukou, vehicle traffic, farming and agricultural processing, as well as residential biomass burning are the main local sources, with conditions worsening when windblown dust events occur. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Fuel burned for winter heating adds an extra layer of particulates on top of other sources.
Are air quality levels in Zhoukou 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.
