May Pen's air quality reflects the flat Clarendon Parish Minho River valley position in central Jamaica, with vehicle traffic on surrounding roads and the bauxite, agricultural, and services corridor contributing local sources. Caribbean trade winds provide background ventilation, while the bauxite mining operations' distinctive mineral dust PM10 represents May Pen's most locally notable air quality contribution and the surrounding tropical agricultural landscape generally maintains moderate Jamaican central corridor readings throughout most of the year.

When is air pollution at its worst in May Pen?
May Pen usually sees its poorest air quality when traffic emissions, mining operations, as well as agricultural activity coincide with periods when dry spells bring strong winds. Dust carried on these winds adds substantially to particulate levels. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in May Pen 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.
