Worst air pollution Packer Park - Philadelphia, today and tomorrow

On 20 September 2026, overall air quality in Packer Park is fair. AQI is the main air quality indicator at 25.7/100. Pollution peaks around 6:00 PM (NO2: 25.7/100).

On 21 September 2026, air quality conditions in Packer Park will be similar to today, with AQI forecast at fair at 27.4/100. Pollution peaks around 2:00 PM (NO2: 27.4/100).

This part of the city typically experiences its worst air quality during the coldest months, driven by the combination of winter heating demand and dense traffic under calm, cold conditions. As temperatures climb, ozone typically becomes the dominant summer issue in this part of the city, as urban heat and sunlight combine with vehicle emissions, sometimes compounded by regional wildfire smoke.

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.

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.
