Zhangye's air quality reflects the Gansu Hexi Corridor's flat oasis position at 1,474 metres between the Qilian Mountains and the Badain Jaran Desert, with vehicle traffic on surrounding roads and the agricultural, food processing, and tourism corridor contributing local sources. Windblown desert dust from the Badain Jaran generates elevated PM10 during spring dust storms, while the elevated Hexi Corridor position aids summer dispersal and Zhangye generally maintains moderate Gansu northwestern corridor readings throughout most of the year.

When is air pollution at its worst in Zhangye?

Zhangye usually sees its poorest air quality when traffic on the surrounding roads, manufacturing and food processing, and agricultural activity coincide with periods when windblown dust events occur. These wind events can carry dust in from the surrounding arid landscape. Such events are most common in the drier shoulder seasons.

Are air quality levels in Zhangye 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.
