Welcome
Welcome to our website for ATTO, the Amazon Tall Tower Observatory – an Amazon research project.
This research site is located in the middle of the Amazon rainforest in northern Brazil, about 150 km north of Manaus. It is run together by scientists from Germany and Brazil. Its aim is to continuously record meteorological, chemical and biological data, such as the concentration of greenhouses gases. With the help of these data, we hope to gain insights into how the Amazon interacts with the overlying atmosphere and the soil below. Because this region is of such importance to the global climate, it is vital to get a better understanding of these complex processes. Only then will we be able to make more accurate climate predictions.
Have a look around on our website to learn more about the research performed at ATTO and in labs and offices around the world. Please note that the website is still under constructions and more content will be added. So be sure to check back soon! You can also follow us on Social Media to get an insight into the daily lives of the ATTO scientists and stay up-to-date on all the latest news and events!

Eliane Gomes Alves and her colleagues measured isoprene emissions at the ATTO 80-meter tower across three years to better understand how these emissions vary seasonally and under extreme climatic conditions like El Niño events. They also looked into which biological and environmental factors regulate the emission of isoprene to the atmosphere.
In a new study, Anne Mendonça, Cléo Quaresma, Daniel Marra and their co-authors analyzed different turbulence regimes at the ZF2 site as part of the ATTO-INVENTA project. They also investigated how turbulence is connected to the occurrence of downdrafts and extreme wind gusts, that might lead to tree mortality.
The summer school Amazon Forests and Global Change is part of the Amazon Tall Tower Observatory (ATTO) project, which investigates forest functioning, biodiversity, forest-atmosphere interactions, and atmospheric chemistry and physics. Its objective is to offer scientific theory and methods to investigate forest functioning, biodiversity, and forest-atmosphere interactions in the context of global change, and takes place at INPA, Manaus and at ATTO Sep 28 – Oct 10, 2023.
the ATTO workshop 2023 will take place in Manaus September 25 - 27, registration is open until August 15.
More soot particles enter the central Amazon rainforest from brush fires in Africa than from regional fires at certain times.
In a new study, Luca Mortarini and his colleagues introduce a novel approach to the study of the roughness sublayer, using a cospectral budget model. Its originality lies in not considering the mixing layer analogy to parameterize the turbulence statistics. In addition, it relates them to the different scales of the wind velocity spectrum without making any assumption on the property of the flow.

Hi everyone, my name is Anna Moraes! I started recently as a Ph.D. student at the National Institute of Amazonian Research (INPA), in Manaus, in the group of Dr. Eliane Gomes Alves. My project focuses on herbivore-induced plant volatiles (HIPVs).
Achim Edtbauer wrote a blog for the Nature Community Ecology and Evolution. He shares insights about how his latest paper came to be, and what it is like to study mosses and lichens at ATTO as an atmospheric physicist.
The Amazon rainforest has an enormous turnover of greenhouse gases. The only way to find out how this turnover will develop over time is to measure it regularly. Therefore, my colleagues and I, recently installed a flask sampler set-up to automatically collect air samples to establish a time series of greenhouse gas measurements at ATTO. My name is Markus Eritt, I am a laboratory head at the ICOS Central Analytical Laboratory in Jena, which is located at the MPI-BGC.
Hello, I am Adriana Simonetti. I just finished my Master in Tropical Forest Sciences at the National Institute for Amazon Research (INPA). I quantified canopy gaps in the Amazon from aerial photographs collected during repeated drone flights. I deeveloped this techinque in the scope of the ATTO project, under the supervision of Dr Daniel Marra.
Hi everybody, my name is Carolina. Since recently, I am a Ph.D. student in the workgroup “Radical measurements” of Hartwig Harder in the atmospheric chemistry department at Max-Planck Institute for Chemistry in Mainz.
My name is Ingrid Chanca and I am a physicist. I am currently pursuing my PhD at the Max Planck Institute for Biogeochemistry, in Jena, Germany and the Universidade Federal Fluminense, in Niterói, Rio de Janeiro. For my research, I am particularly interested in radiocarbon. To be able to measure radiocarbon in air samples, I have built the GASPS, a Gas Samples’ Purification System.
