Mossoró's air quality benefits from its position on the Rio Grande do Norte semi-arid coast, with consistent Atlantic northeast trade winds providing reliable maritime ventilation across this major salt and petroleum production city. Wind power generation from the surrounding extensive wind farm complex is evidence of the consistent ventilation, while vehicle emissions from the BR-304 and petroleum extraction operations from the Mossoró oil field are the primary local air quality sources.
