Las Maravillas in Chiapas reflects the flat Chiapas agricultural corridor position, with vehicle traffic on surrounding roads and agricultural operations contributing modest local sources. The tropical climate's frequent convective rain provides periodic atmospheric cleansing, while the flat terrain allows reasonable dispersal and the relatively low industrial density generally maintains moderate to good conditions throughout most of the year.

When is air pollution at its worst in Las Maravillas?
Pollution in Las Maravillas typically rises when traffic emissions along with agricultural activity combine, especially once dry, windy weather picks up. Dust carried on these winds adds substantially to particulate levels. This is most noticeable during spring and autumn wind events.
Are air quality levels in Las Maravillas 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.
