Humid southwestern mississippi air is what shapes air quality most in Brookhaven, and spring pine pollen brings a heavy yellow dusting. That mix of factors is fairly representative of towns in this part of the country. As with most US destinations, conditions here are best understood by season rather than by a single yearly average.

When is air pollution at its worst in Brookhaven, Mississippi?
Air quality in Brookhaven shifts across the year — the mildest, cleanest weather typically arrives in winter, whereas heat, humidity, and the local petrochemical industry combine to drive both ozone and particulate levels up for much of the summer. Industrial corridors nearby tend to see more persistent background pollution than surrounding suburban areas.
Are air quality levels in Brookhaven, Mississippi 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.
