Haicheng's air quality reflects the Liaoning Haicheng River valley's industrial position adjacent to Anshan, with vehicle traffic on surrounding roads and the steel, magnesia, and manufacturing corridor generating elevated industrial PM2.5. The valley's topographic variation creates limited concentration under inversions, while the proximity to Anshan's steel complex creates a shared regional industrial background and winter coal heating maintains moderate to elevated Liaoning industrial southern corridor readings throughout the year.

Frequently Asked Questions
Is air quality bad in Haicheng right now?
On 10 August 2026, overall air quality in Haicheng is fair. O3 is the main pollutant at 26.4/100. Pollution peaks around 12:00 AM (NO2: 44.9/100).
Will air quality be worse tomorrow in Haicheng?
On 11 August 2026, air quality conditions in Haicheng will be worse than today, with AQI forecast at poor at 74.8/100. Pollution peaks around 11:00 PM (NO2: 74.8/100).
When is air pollution at its worst in Haicheng?
Haicheng usually sees its poorest air quality when traffic emissions, heavy industrial and chemical processing, together with manufacturing and food processing coincide with periods when temperature inversions set in over the valley. The bowl-like terrain here limits how quickly pollutants can escape. These wind events can carry dust in from the surrounding arid landscape.
Are air quality levels in Haicheng 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.
