Mafra's air quality in Brazil reflects the Serra Gaúcha highlands border between Santa Catarina and Paraná at 815 metres, with vehicle emissions from the BR-116 and surrounding timber, paper, and agribusiness operations contributing local sources. The elevated plateau position aids background dispersal, while cold winter temperature inversions in the southern Brazilian highlands and dry season burning from surrounding agricultural and timber operations contribute seasonal PM2.5 variation throughout the year.
