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!
The German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig is looking for a Postdoc in remote sensing, biodiversity science and atmospheric chemistry.
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).
BVOC emissions in the Amazon have been studied for decades, but we still don’t fully understand when and under what conditions tree species or even individual trees emit more or fewer isoprenoids. To address this, Eliane Gomes Alves and her colleagues measured isoprenoid emission capacities of three Amazonian hyperdominant tree species.
In a new study, Marco A. Franco and his colleagues analyzed when and under what conditions aerosols grow to a size relevant for cloud formation. Such growth events are relatively rare in the Amazon rainforest and follow and pronounced diurnal and seasonal cycles. The majority take place during the daytime, and during the wet season. But the team also discovered a few remarkable exceptions.
Rio de Janeiro’s science museum, the Museu do Amanhã (Museum of tomorrow) currently presents a special exhibition on the Amazon. Titled “Fruturos - Tempos Amazônicos”. The exhibition will be open to visitors until June 12, 2022, and includes an immersive ATTO experience.
The Brazilian Minister for Science, Technology and Innovation Marcos Pontes, took ambassadors to see MCTI projects in the Amazon and announces about R$ 90 million investment in the region. It will be used to build 50 modern laboratories, improve the infrastructure of the ATTO tower and pay for research grants to study the Amazon rainforest via a CNPq call.
It is long known that aerosols, directly and indirectly, affect clouds and precipitation. But very few studies have focused on the opposite: the question of how clouds modify aerosol properties. Therefore, Luiz Machado and his colleagues looked into this process at ATTO. Specifically, they studied how weather events influenced the size distribution of aerosol particles.
Mosses and lichen appear to play a previously overlooked but important role in the atmospheric chemistry of tropical rainforests. A new study from Achim Edtbauer and colleagues shows that such cryptogams emit highly reactive and particle-forming compounds (BVOCs) that are important for air quality, climate, and ecosystem processes.
Blog: Voices from the Amazon
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.
Hi there, my name is Renato Braghiere! I’m a climatologist and global ecologist at NASA Jet Propulsion Laboratory in California and I have worked on the ATTO project during my MSc degree from 2011 to 2013. I grew up in the countryside of the state of São Paulo in Brazil amid the trees, and from my early years, I’ve been curious about how nature works and how we connect with nature in so many different ways.
