Santo Domingo's air quality reflects the flat Dominican Republic Caribbean coastal position on the Ozama River at sea level, with vehicle traffic on surrounding roads and the vehicle density, industrial, and port corridor generating elevated PM2.5. Consistent Caribbean northeast trade winds provide maritime ventilation, while the tropical climate's convective rain provides periodic cleansing and Santo Domingo generally maintains moderate Caribbean coastal capital readings with better conditions than enclosed Cibao valley cities throughout most of the year.

When is air pollution at its worst in Santo Domingo?
In Santo Domingo, road traffic together with fishing fleet activity are the main local sources, with conditions worsening when dry, windy weather picks up. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Santo Domingo 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.
