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!
Soot and other aerosols from biomass burning can influence regional and global weather and climate. Lixia Liu and her colleagues studied how this affects the Amazon Basin during the dry season. While there are many different interactions between biomass burning aerosols and climate, they found that they overall lead to fewer and weaker rain events in the Amazon rainforest.
My name is Eva Pfannerstill, and I studied OH reactivity in different environments, including the Amazon rainforest. When I first opened the lid of the Comparative Reactivity instrument, I felt like looking at a bowl of Teflon spaghetti: The dozens of thin tubes, valves and mass flow controllers inside make up a confusing network for gas flows and reactions. Its purpose is the measurement of the so-called total OH reactivity. The OH reactivity tells us how much hydroxyl (OH) radicals are lost per unit of time in ambient air.
A new study by Löbs et al. in Biogeosciences documents the microclimatic conditions for tropical mosses as a baseline for studies on their overall relevance on biogeochemical cycling. They found that water and light are overall the most important requirements for them to become photosynthetically active. However, their habitat determines which of the two plays the bigger role.
We are happy to announce that we will once again convene a session on Amazon Rainforest research at the EGU General Assembly 2021. The session is titled “The Amazon – a biome of global significance in transition”. Just in time for the call for abstracts, the EGU has announced, that the General Assembly 2021, traditionally held each spring in Vienna, Austria, will instead take place entirely online once more.
Nora Zannoni and her colleagues measured BVOC emissions at the ATTO tall tower in several heights. Specifically, they looked at one particular BVOC called α-pinene. They found that chiral BOVs at ATTO are neither equally abundant nor is the ratio of the two forms constant over time, season, or height. Surprisingly, they also discovered that termites might be a previously unknown source for BVOCs.
Chamecki and his co-authors analyzed if the gentle topography underneath the Amazon rainforest impacts atmospheric turbulence. They published their results Open Access in the Journal of the Atmospheric Science.
This year, we are celebrating the anniversaries of two milestones at ATTO. Our tall tower is celebrating its fifth birthday tomorrow. On 15 August 2015, it was officially inaugurated. However, measurements at the station already started in August 2010 on two smaller towers. Since then, the observatory has continued to grow. Now more than 200 scientists worldwide participate in this interdisciplinary project on climate research in the Amazon.

Hello! My name is Camila Lopes. I’m a meteorologist working in the ATTO Project since 2020. It is part of my Ph.D. studies at the University of São Paulo, Brazil, under the supervision of Prof. Rachel Albrecht. I’m involved in a project to study the lifecycle of clouds and aerosols in the Amazon by measuring their properties in several locations. One of these locations includes the ATTO Tower and a new site assembled about 4-km away from the tower. The site is called "Campina", which means "meadow" in Portuguese.
Shujiro Komiya is a postdoc at MPI-BGC. He got his degrees at Meiji University in Tokyo and has a background in studying greenhouse gas dynamics in rice paddy fields. He now applies this in the Amazon rainforest at ATTO.
Eva Pfannerstill remembers her time in the ATTO project, and what it was like to perform research at a remote site in the Amazon Rainforest. The article was first published on EGU Blogs.
Marco Franco is a PhD student at the University of São Paulo (USP), in São Paulo, in the group of Prof. Paulo Artaxo. For his thesis, he studies the properties of aerosols in the Amazon and how they vary with height.
My name is Stefan! I’m a meteorologist and I have been working on the ATTO project since 2010. I heard about the Amazon Rainforest for the first time in my childhood. From that moment on I was really enthusiastic about this abundant ecosystem and passionate to get to know it.
