Lagoa Santa's air quality benefits from its elevated position in the Minas Gerais karst plateau at 761 metres north of Belo Horizonte, with vehicle emissions from the BR-040 and the surrounding limestone quarrying, university research, and residential character contributing local sources. The Belo Horizonte basin's poor dispersal characteristics partially influence this northern metropolitan corridor, while the elevated karst plateau position generally provides marginally better conditions than the enclosed metropolitan basin below.

Are air quality levels in Lagoa Santa 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.
