"ATTO" stands for Amazonian Tall Tower Observatory. The German-Brazilian joint project was launched in 2009 and is coordinated by the Max Planck Institute for Chemistry. The tower aims at delivering groundbreaking findings which will be the basis for improved climate models. With a height of 325 meters the tower extends the ground-level boundary layer, and provides information taken from approximately 100 squarekilometers from the world´s largest forest area.
The Amazon region is of global significance: it produces big amounts of oxygen and impacts the water cycle through evaporation and stabilize the climate.
ATTO is the counterpart of the 2006 completed ZOTTO tower that stands in Siberia and the the Max Planck Institute of Chemistry is also involved. ATTO is integrated into an existing structure of smaller Brazilian measuring towers. The cost for the construction of ATTO including the first five years of running costs is estimated to be 8.4 million €. which will be financed by Germany and Brazil in equal parts.
