Harbin's air quality reflects the flat Heilongjiang Songhua River plain's Northeast China position, with vehicle traffic on surrounding expressways and the food processing, pharmaceutical, and industrial corridor contributing local sources. Winter residential coal heating extensively compounds industrial emissions under frequent severe anticyclonic inversions in this extremely cold Northeast China city, while summer conditions are considerably better and Harbin generally maintains among China's more seasonally contrasted winter heating-challenged provincial capital environments throughout the year.

On 11 August 2026, air quality conditions in Harbin will be similar to today, with AQI forecast at fair at 35.0/100. Pollution peaks around 12:00 PM (O3: 35.0/100).
When is air pollution at its worst in Harbin?
The biggest local contributors to pollution in Harbin are vehicle traffic and manufacturing and food processing, particularly once dry spells bring strong winds. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Residential heating through the colder months is a major seasonal source of particulates.
Are air quality levels in Harbin 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.
