Blog: Voices from the Amazon

Jeová can create an ultra-realistic simulation of the Amazon rainforest and the ATTO tower with the model DART.

Hello everyone, my name is Jeová Ramos da Silva Junior. I am a meteorologist and had my first contact with ATTO at the beginning of my master’s degree in 2017. During this period, I investigated how biomass burning might affect photosynthesis inside the canopy of the Amazon Rainforest.

Maria Prass in the forest at ATTO to study bioaerosols

My name is Maria Prass and I’m a PhD student at the Max Planck Institute for Chemistry in Mainz in the group of Christopher Pöhlker who’s focused on aerosol analytics. Born in the countryside, the forest and all its small to large inhabitants are fascinating me up even today. Studying biology seemed to be the perfect match for me. Who would have thought, that this would move me to be a scientist in the most beautiful but at the same time endangered ecosystem in the world: the Amazon rainforest?

I successfully unscrewed the CRM from the instrument rack in the lab container...

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.

Campina site to study the lifecycle of clouds and aerosols 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.

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.

Akima climbs the tall tower to the top to maintain the instrument.

Hi, my name is Akima! I studied meteorology at the University of Frankfurt. But back then I realized that I would love to work in the field instead of only sitting at my desk. When I was looking for options after graduation, there was an opportunity to participate in the ATTO project. I thought this was a fantastic chance to combine my background with exciting fieldwork and so I became PhD student at MPI-C in Mainz.

Eliane measures VOC emissions of leafs with the IRGA, a gas analyzer.

I’m Eliane Gomes-Alves. I have been working at ATTO since 2015 with measurements of plant emissions of Volatile Organic Compounds (VOC). To sample VOC emissions, we use equipment that was originally developed to measure gas exchanges between the air and plant leaves. It is called IRGA – infrared gas analyzer.

My name is Andrew Crozier and I have been the Site Engineer in the ATTO project for the last 6 years. Now my time with the ATTO project is coming to a close. And though I am saddened to leave it, I will always be grateful for the life-changing experiences I have had while connected with it.

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.

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.

Pedro climbing in the Amazonian trees to collect data

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.

Olaf Kolle is responsible for field installations at ATTO.

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.

PostDoc Hella on the ATTO tall tower

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 investigate secondary organic aerosol formation from the oxidation of Biogenic VOCs and their subsequent photochemical processing.

Denis with him sampling filter

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.
