New Publication: Footprint region of ATTO

Christopher Pöhlker and co-authors published an extensive new paper, characterizing the footprint region of ATTO. They hope that fellow researchers in the Amazon region can use this publication as resource and reference work to embed ATTO observations into a larger context of Amazonian deforestation and land use change. Pöhlker et al. published the paper Open Access in Atmospheric Chemistry and Physics Volume 19.

In their study, they used backward trajectories to first define the ATTO footprint region. With this modeling approach, you can trace air masses in the atmosphere back along their presumed transport path to ATTO. Because the source regions of observed trace gases and aerosols might be thousands of kilometers away, they did not necessarily trace it all the way back.

Two PhD projects available at MPI-BGC Jena

Both PhD project is part of the International Max Planck Research School for Global Biogeochemical Cycles (IMPRS-gBGC) at the Max-Planck-Institute for Biogeochemistry in Jena, Germany.

In cooperation with the Friedrich Schiller University Jena, the Max Planck Institute for Biogeochemistry houses a unique and flexible research program that grants German and foreign students a broad selection of learning opportunities while still maintaining a research focus. The IMPRS-gBGC offers a PhD program specializing in global biogeochemistry and related Earth System sciences.

The first project is directly related to ATTO. Supervisors are Dr. Jost Lavric and Prof. Susan Trumbore. The second project is partially related to ATTO, but will also incoorporate other research projects.

New Publication: Human influence on particulate matter in the Amazon

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.

They analyzed the concentration, composition and properties of particulate matter in the central Amazon. As part of the GoAmazon campaign, they collected data during the dry season, when burning events are most frequent.… Continue reading
