During 14-29 May 2025 our group was involved in a boat campaign, measuring air quality and meteorological parameters on a boat over a 1.300 km roundtrip journey between Manaus and Tefé, through the Solimões River.

This expedition was made possible by a partnership between the USP and UEA teams, as well as the Mamirauá Institute, allowing us to extend our measurements even further towards the Western Amazon region.
