![Viewover the Rainforest around ATTO (Amazinian Tall Tower Observatory) View from the large 300 metre ATTO tower (Amazonian Tall Tower Observatory), which casts a long shadow, over to the so-called instant tower, which is about 80 metres high, and the tripod mast next to it. Green rainforest in every imaginable shade of green as far as the horizon, with a few dead trees in between. A few white clouds drift across the blue sky and cast shadows here and there on the jungle, which from this height is somewhat reminiscent of broccoli.](/5760477/header_image-1703160210.jpg?t=eyJ3aWR0aCI6ODQ4LCJoZWlnaHQiOjMwNywiZml0IjoiY3JvcCIsImZpbGVfZXh0ZW5zaW9uIjoianBnIiwib2JqX2lkIjo1NzYwNDc3fQ%3D%3D--51e354c738e131ea4f9b5701e7016be2e0727d8b)
ATTO - Amazonian Tall Tower Observatory in 2023
Together with our Brazilian and Mainz colleagues, we are contributing to the infrastructure that enables the researchers and workers there to carry out their activities on site with the greatest possible safety and reliability.
During this trip, we increased safety when climbing the 300 metre tower, carried out repairs and maintenance on many measuring devices and equipment and installed a fog collector (a generous loan from the University of Münster).... collected samples, met colleagues in Manaus and then some of our group travelled on to Tanguro (Brazil).

To the right is a covered container. And from the bottom right to the top centre of the portrait format image is the scaffolding tower, which is painted alternately orange and white every 12 metres. There is a stairwell in the tower with an accompanying safety rail (INNOTECH) and the tower is hollow in the centre with a rail for a one-person lift. There is also a lift rail on the corner spar facing the tower on which a robot lift regularly measures profiles on a scientific mission. The tower is surrounded by trees up to 40 metres high. The sky is mostly white in the photo, interspersed with a few patches of blue.](/5760204/original-1703157150.jpg?t=eyJ3aWR0aCI6MjQ2LCJvYmpfaWQiOjU3NjAyMDR9--b6ccf25e6869bd8ad4a17474becd460ccbd77e56)
