Huanglongsi's air quality reflects the flat central Henan agricultural and urban corridor, with vehicle traffic on surrounding roads and agricultural processing and industrial operations contributing local sources. Winter residential coal and biomass burning generates elevated PM2.5 under inversions, while the flat North China terrain allows reasonable summer dispersal and the regional industrial background elevates winter readings throughout the year.

When is air pollution at its worst in Huanglongsi?

Air quality in Huanglongsi tends to be worse when vehicle traffic, agricultural burning, as well as residential biomass burning build up and 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 Huanglongsi 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.
