Terras da Comporta Dunas Course air quality benefits from its exceptional Comporta Atlantic Ocean and Sado Estuary dual-coastal position south of Setúbal, with consistent Atlantic westerlies providing outstanding maritime ventilation through the extraordinary Comporta pine forest and dune landscape. Vehicle traffic contributes very modest local sources, while the extraordinary coastal dune and pine forest setting generally maintains excellent to good conditions throughout most of the year.

When is air pollution at its worst in Terras da Comporta – Dunas Course?

South of Lisbon in the Comporta rice-growing region, golfers mainly notice the area's rural tranquility, with minimal traffic and only a brief late-winter pine and dune scrub bloom to plan around. Summer's dry conditions from May keep the air consistently clean.

Are air quality levels in Terras da Comporta – Dunas Course 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.
