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!

When forests burn those fires produce a lot of smoke. And that smoke usually contains soot, also called “black carbon”. Black carbon particles are aerosols that absorb radiation and as such can warm the Earth’s atmosphere and climate. But we still have much to learn about aerosols, their properties, and distribution in the atmosphere. One of those things is the question of how black carbon emitted from biomass burning in Africa (i.e. forests, grasslands, savannas etc.) is transported across the Atlantic and into the Amazon basin, and what role it plays there. Bruna Holanda and her co-authors tackled this in their new study published in ACP.

My name is Sebastian and I am a biologist participating in the ATTO project since 2017. At the moment I am working on my master thesis on "Bioaerosol emission patterns of tropical fungi in the Amazon”Bioaerosols are particles in the atmosphere originating from a biological source, for example fungal spores, bacteria and viruses. The fungal spores are what interests our research team. Together with multiple colleagues, in particular Nina Löbs and Cybelli Barbosa, I developed a measurement setup, with which we can quantify and analyze fungal particle emissions in the field and in the lab.

News

The April newsletter includes a few important announcements, including one about the plans for this year's ATTO workshop! All regular formats, such as New Publications and Meet the Team are back of course.
We have minimized our field activities at ATTO due to COVID-19 since last week. Researchers will not travel to ATTO to collect samples or make measurements until further notice. For now, a small core team will continue taking care of our long-term measurements.
The EGU is officially announcing the cancellation of the physical EGU General Assembly 2020 in Vienna, Austria. Instead "Sharing Geoscience Online" will allow abstract authors to share presentation materials and open these for live discussion as well as participate in a selection of online networking events. We are also planning additional activities that will extend into the rest of the year and will provide more information about all of these events in the coming weeks.
We have recently taken a big step to further expand our research with the INVENTA/ATTO project to study. Led by Daniel Marra and Susan Trumbore, we want to investigate wind-tree interactions in the Amazon. Our goal is to integrate research on tree architecture and bio-mechanics with atmospheric and biogeochemical processes.
You may have noticed that the front page of our website got a new look recently. This is because in addition to project news, we now also have a blog! It is called "Voices from the Amazon", and here you will hear directly from our ATTO team. You can find it right below the "News section" on the front page. We are kicking things off with a very special post for today's Day for Woman and Girls in Science.
Fungal spore emissions are an important contributor to biogenic aerosols, but we have yet to understand under what conditions fungi release their spores. Nina Löbs and co-authors developed a new technique to measure emissions from single organisms and tested this out at ATTO and with controlled lab experiments. They published their results in the Open Access Journal Atmospheric Measurement Techniques.

Blog: Voices from the Amazon

The news reaching us from Brazil, and in particular from Manaus, these days are very grim. On behalf of the ATTO partners from Germany and elsewhere, I would like to express our concern and support for our colleagues in Brazil.
Hello everyone, my name is Pedro. I am a biologist and a lover of the world of plants. I first realized this during my undergrad. As an intern at the Institute of Botany of São Paulo, I participated in an ozone bio-monitoring project. Basically, it was all about exposing sensitive plants to this pollutant, ozone, in several locations around an oil refinery. After a few days of exposure, I looked at the leaves and checked if and to what degree they have injured due to the ozone.
My name is Olaf Kolle and I am the scientific head of the Central Service Group ‘Field Experiments and Instrumentation’ at the MPI-BGC in Jena. Currently, we are 13 people in this Service Group. I myself am a meteorologist. But our group members have a wide range of backgrounds, from scientists over gardeners to engineers. This means that we have accumulated a large amount of technical and scientific expertise to plan, set up and maintain field installations.
Hello everybody, my name is Hella van Asperen. I am a PostDoc at the Institute of Environmental Physics in Bremen (Germany), in the group of Prof. Notholt, but currently live and work in Manaus. I started my studies at Wageningen University in the Netherlands with the Bachelor program ‘Soil, Water, Atmosphere’. That I followed with a Masters in ‘Soil Science’ and ‘Earth System Science’.
Hello everybody, I am Milena Ponczek. I am a post-doc at the Laboratory of Atmospheric Physics at the University of Sao Paulo. About one year ago, I joined Prof. Artaxo’s group there. For my current project that includes ATTO, we focus on aerosols life cycle in the Amazon. I investigate secondary organic aerosol formation from the oxidation of Biogenic VOCs and their subsequent photochemical processing.
Hello together. My Name is Denis Leppla and I am working at ATTO since 2017 with rather simple instruments for filtering aerosol particles from the air. There we analyze them with a mass spectrometer at the Max Planck Institute for Chemistry in Mainz. With this analysis, we can get insights into the chemical composition of aerosol particles and identify hundreds of different compounds.
