Vacaria's air quality reflects the Rio Grande do Sul Serra Gaúcha plateau at 971 metres in the apple and grape producing highlands, with vehicle emissions from the BR-285 and surrounding fruit farming, livestock, and agribusiness operations contributing local sources. The elevated plateau position aids background dispersal, while cold winter temperature inversions in the southern Brazilian highlands add seasonal wood-burning PM2.5 and dry season burning from surrounding agricultural operations contributes seasonal variation throughout the year.
