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!

Convective storms often occur in the tropics and have the potential to disturb the lower part of the atmosphere. They might even improve the venting of trace gases out of the forest canopy into the atmosphere above. To better understand these processes, Maurício Oliveira and co-authors used the infrastructure at ATTO to study storm outflows during nighttime. They published the results in a new paper in the Open Access Journal Atmospheric Chemistry and Physics.

We hear a lot about particulate matter these days, mostly in the context of air pollution in inner cities. But what about particulate matter in the Amazon rainforest? Well, the short answer is that particulate matter is present in the air above the Amazon, too. And although its concentrations are lower than those in large cities, urbanization and deforestation fires have a significant impact. To find out what that impact exactly is, was the aim of a new study by Suzane de Sá and co-authors.
Felipe Souza and co-authors now collected bioaerosols at our ATTO site. Then they extracted and analyzed the DNA to determine the communities present. This is the first study that described the community of microorganisms within aerosols in the Amazon. They found many different types of bacteria and fungi. Some were cosmopolitan taxa, but they also identified many that are specific to certain environments such as soil or water. This suggests that the atmosphere may act as an important gateway for bacteria to be exchanged between plants, soil, and water.
The Amazon rainforest interacts with the atmosphere by exchanging many substances. Many of these, such as carbon dioxide, methane, ozone, and organic compounds, are produced by the vegetation. They are very influential in both the regional and global climates. Until now, the estimates of their emission and absorption rates are based on classical theories. But those were developed over relatively short vegetation and are valid for the so-called “inertial sublayer.”
We’re excited to announce that this year our annual ATTO …
