Mora in Costa Rica reflects the Heredia Province's Central Valley position at 1,070 metres, with vehicle traffic on surrounding roads and the coffee, agricultural, and services corridor contributing local sources. The Costa Rican volcanic highland's topographic variation provides natural ventilation, while the tropical climate's frequent convective rain provides effective atmospheric cleansing and Mora generally maintains good to moderate Costa Rican central plateau readings throughout most of the year.

When is air pollution at its worst in Mora?

Pollution in Mora typically rises when vehicle traffic and agricultural burning combine, especially once weather conditions turn unfavourable. Background emissions and local weather both shape how conditions change from day to day. Local weather patterns add further day-to-day variation.

Are air quality levels in Mora 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.
