Site T2 was designed to sample the fresh Manaus pollution plume during the GoAmazon 2014/5 experiment. This sampling site was placed at the TIWA hotel, Iranduba-AM (3° 8'21.12"S, 60° 7'53.40" W) ~ 10 km southeast of the downtown city, at the Negro River bank. The site was equipped with an instrumented container to monitor the physical and chemical properties of particles and gases on the outflow of pollution plume from the city.
T2 site at the Tiwa Hotel, on the Negro River western bank, 5-8km downwind of Manaus.
