San Ignacio's air quality reflects the central Paraguayan Misiones department agricultural region, with vehicle traffic on the Ruta 1 and surrounding cattle, soybean, and agricultural operations contributing local sources. The flat Misiones plateau terrain generally allows reasonable dispersal, while dry season burning from surrounding Paraguayan agricultural land contributes seasonal PM2.5 variation and the rural agricultural character generally maintains relatively good baseline conditions compared to the greater Asunción metropolitan corridor throughout most of the year.

Are air quality levels in San Ignacio 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.

Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
