Puxi in China reflects the Shanghai metropolitan area's western Huangpu River corridor, with vehicle traffic and dense urban commercial and residential character contributing elevated NOₓ. East China Sea breezes provide limited maritime ventilation, while winter anticyclonic inversions concentrate emissions and Puxi generally maintains moderate to elevated Shanghai metropolitan readings throughout most of the year.

When is air pollution at its worst in Puxi?
In Puxi, traffic on the surrounding roads is the main local source, with conditions worsening when maritime winds die down. Sea breezes typically keep conditions in check, except during still weather. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Puxi 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.
