Barra do Corda's air quality reflects the Maranhão semi-arid interior at the Cerrado-Caatinga transition, with vehicle emissions from the BR-226 and surrounding babaçu palm, agricultural, and cattle ranching operations contributing local sources. Dry season burning from surrounding Maranhão agricultural and Cerrado land contributes seasonal PM2.5 variation, while the flat Maranhão interior generally allows reasonable wind dispersal on most days throughout the year.
