Since The Heights is a historic residential district on a low ridge northwest of downtown, its air quality mirrors Houston overall rather than following a separate local pattern. Local traffic and immediate surroundings can shift day-to-day readings slightly from the citywide figure.

When is air pollution at its worst in The Heights?
This neighborhood in Houston sees air quality shift through the year. Typically, between summer heat and winter cedar season, spring and fall offer the most moderate conditions, while extended summer heat waves bring the year's worst ozone readings in the state's biggest metro areas. Gulf Coast humidity and inland heat can each add their own seasonal pollution patterns.
Are air quality levels in The Heights 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.
