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!
This October, scientists from the ATTO project met in Manaus, Brazil for our project workshop. It clearly confirmed that ATTO has developed into a research site with globally unique capabilities – despite the pandemic and challenging field conditions. It was the first in-person workshop since the start of the pandemic and many project members had met in person for the first time since early 2020. For this reason alone, the spirits were high.
The team around Cybelli Barbosa analyzed and studied the distribution patterns of giant bioaerosol particles in the Amazon. For this, they looked at over 500 000 individual particles from five years and eight intensive campaigns and made some exciting discoveries, now published in npj Climate and Atmospheric Science.
Bioaerosols influence the dynamics of the biosphere underneath. In a new study, Sylvia Mota de Oliveira and her colleagues used the ATTO site to collect air samples at 300 m above the forest. Then, they used DNA sequencing to analyze the biological components that were present and figure out what species of plant or fungi they belong to. One of the most striking new insights is the stark contrast between the species composition in the near-pristine Amazonian atmosphere compared to urban areas.
Eiky Moraes, Cléo Dias-Júnior and their colleagues wanted to find out if the local topography at the ATTO influenced the atmospheric movements. In particular, they were interested in the effect that topography has on the formation of gravity waves. Comparing two simulations, one with and one without topography, revealed some important differences in the dynamics and chemistry of the atmosphere.
We announce an open postdoc position for a plant ecologist/ecophysiologist in the ATTO project to work on cryptogamic communities and their role in CO2 and water cycling in the Amazonian rainforest. The call will be open until filled.
We are pleased to inform all ATTO researchers that this year, we hold our annual workshop again in person this year. Like in 2019, the INPA in Manaus will be our host. The workshop will take place October 3 - 6, with the option for an overnight excursion to ATTO the following day. Registration is now open.

I want one! This was the enthusiastic reaction of a Brazilian student after her first encounter with a scintillometer at the CloudRoots campaign in Amazonia. The scintillometer is indeed a special instrument that deserves admiration.
I am Subha and I like to call myself an interdisciplinary researcher. I did civil engineering for my bachelor’s degree, and for my master’s degree, I worked on the applications of remote sensing and GIS. Now I work full-time at Max Planck Institute for Chemistry in Mainz with a wonderful team led by Christopher Pöhlker.
My name is Stefanie Hildmann and I am currently a PhD student in the group ‘Organic Trace Analysis’ of Prof. Thorsten Hoffmann at the Johannes Gutenberg – University of Mainz (Germany). In my PhD, I want to characterize secondary organic aerosols (SOA) chemically at the molecular level.
Hi, my name is Viviana Horna. This April 2022 I started working at the Max Planck Institute for Biogeochemistry as the new scientific coordinator of the ATTO project. I studied tropical forestry in Peru for my BSc, where I am from.
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.
