Sanhe's air quality reflects the flat Hebei North China Plain position adjacent to Beijing's eastern metropolitan corridor, with vehicle traffic and the manufacturing, logistics, and residential corridor contributing local sources. The Beijing-Tianjin-Hebei regional background and winter anticyclonic inversions elevate readings and Sanhe generally maintains moderate to elevated Beijing eastern metropolitan fringe readings throughout the year.

When is air pollution at its worst in Sanhe?
In Sanhe, traffic emissions and light manufacturing are the main local sources, with conditions worsening when still air allows pollutants to build up. Day-to-day conditions here depend heavily on the weather. Local weather patterns add further day-to-day variation.
Are air quality levels in Sanhe 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.
