Amazon Tall Tower Observatory

Additionally, there are climate-controlled containers for laboratory equipment and an office, a base camp and nearby sites for studying vegetation and soil processes.

The nearest large urban area is the city of Manaus in the state Amazonas, about 150 kilometres (93 mi) southwest of the ATTO site.

During the dry season, the wind direction shifts and puts the ATTO site within the influence of Manaus and the "arc of deforestation" and air pollution is noticeable even here.

According to the German Federal Ministry of Education and Research (BMBF), ATTO enables new levels of measurements of the complex interactions between the land surface and the atmosphere.
