Worst air pollution Nan Tien Gratitude Bell - Berkeley, today and tomorrow

On 10 September 2026, overall air quality in Nan Tien Gratitude Bell is good. AQI is the main air quality indicator at 15.9/100. Pollution peaks around 3:00 PM (O3: 15.9/100).

On 11 September 2026, air quality conditions in Nan Tien Gratitude Bell will be similar to today, with AQI forecast at good at 18.8/100. Pollution peaks around 12:00 PM (O3: 18.8/100).

This area typically sees its worst air quality during the winter season, driven by heating season smoke that lingers under stagnant, cold winter air. Summer shifts the concern toward bushfire smoke here too, as hot, dry summers raise both bushfire risk and the ozone formed from strong sunlight. The shoulder seasons, spring and autumn, usually offer the year's best air quality thanks to milder, breezier conditions.

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.
