SmogRank / Brazil

Air quality in Barra Longa

Minas Gerais, Brazil. Measured until 31 Dec 2025; not measured today, so it is only on past boards. We make model estimates only for places of 15,000 people or more.

Its measured days

SmogRank measured Barra Longa with ground monitors from MonitorAr (Brazil's Ministry of the Environment) from 1 Jan 2023 to 31 Dec 2025: 954 days, averaging 8.3 µg/m³. Its monitors stopped giving readings we can use, so it isn't ranked today, but those days stay on the past boards: 954 day boards.
