In H.W. Smith Building, light traffic and open farmland nearby mean seasonal dust and burning outweigh congestion as a pollution source here. This is partly offset by nearby tree cover, which filters out some particulate matter naturally. Broader regional monitoring generally reflects this same baseline, with small local variation. Daily conditions can shift noticeably depending on wind, temperature, and traffic patterns.

Frequently Asked Questions
Is air quality bad in H.W. Smith Building right now?
On 20 September 2026, overall air quality in H.W. Smith Building is very poor. AQI is the main air quality indicator at 93.9/100. Pollution peaks around 11:00 PM (PM10: 93.9/100).
Will air quality be worse tomorrow in H.W. Smith Building?
On 21 September 2026, air quality conditions in H.W. Smith Building will be similar to today, with AQI forecast at very poor at 100/100. Pollution peaks around 8:00 PM (PM2.5: 100/100).
When is air pollution at its worst in H.W. Smith Building?
December through February tends to be calm here, with wind speeds averaging around 13 km/h and temperatures near 19°C -- conditions cool and still enough for particulate matter and smoke to settle near the ground instead of dispersing. Between June and August, average temperatures reach around 28°C here, warm enough for intense heat and sunlight to fuel ground-level ozone formation.
Are air quality levels in H.W. Smith Building 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.
