12 July, 2018

I am Saqr Munassar, from Yemen. I started working from the 1st of July, 2018 as a PhD candidate in the ATM working group led by Christoph Gerbig along with the SRS group led by Julia Marshall. I conduct a project on developing preoperational mesoscale inverse modelling system for quantifying GHGs’ sources and sinks.

I moved to Germany at the end of 2014 for pursuing the Master studies at the Environmental Physics Institute (IUP), University of Bremen. My Master’s thesis was specified for studying the cloud impacts on tropospheric retrievals observed from space-based remote sensing monitoring. After being awarded the Bachelor degree with the first rank in Physics at the University of IBB (IBB, Yemen), I had been appointed as an academic member in the Physics department since 2010. During the period 2010 – 2014, I was working on teaching a couple of practical physics courses as well as joined a research team carrying out projects on nanomaterials and their application in the environment (resulted in publishing two scientific papers).

Currently, my research interest is mainly focused on enhancing the quantification of the GHGs exchange between the surface and the atmosphere, in particular Bio-Atmospheric regional fluxes, using the state-of-the-art of numerical models. Additionally, developing cloud product algorithms for satellite measurements is an interest for a better quantification of tropospheric retrievals, including GHGs, with a good tempo-spatial resolution.

I look forward not only to learning from such a scientific leading constitution but also to exchanging the knowledge and expertise in relation to promoting the protection of climate system and vulnerable ecosystems on our fascinating Earth’s Planet.

+ Europe-wide research flights focus on greenhouse gas methane
1 June, 2018

The CoMET research mission measures the two most important greenhouse gases carbon dioxide (CO2) and methane (CH4) in the atmosphere. The specially equipped aircraft will examine the airspace from Europe to North Africa from mid-May to mid-June 2018. Led by the German Aerospace Center (Deutsche Zentrum für Luft- und Raumfahrt DLR), the mission is carried out in cooperation with the Max Planck Institute for Biogeochemistry, Jena, and the universities of Bremen and Heidelberg.

+ Ambarchik video
26 January, 2018

The Arctic is warming due to climate change. What are the consequences for greenhouse gases in the atmosphere? Friedemann Reum and Mathias Göckede from the Max Planck Institute for Biogeochemistry want to find out. They measure greenhouse gas concentrations in the air on-site - in the remote locality Ambarchik, at the Siberian coast of the Arctic Ocean. With their data they calculate how much carbon dioxide and methane escapes from the permafrost soils of the Siberian Arctic into the atmosphere.

Friedemann Reum and Mathias Göckede explain their research on permafrost in a remote locality in the Siberian Arctic in this new educational video on Youtube (English version/German version)

Mission Statement

Biogeochemical cycles are represented in the atmosphere by several important greenhouse gases, such as carbon dioxide, methane and nitrous oxide. In the Department of Biogeochemical Systems we develop methods to measure these gases in situ and by remote sensing, we expand the measurement network to remote hot-spot regions such as Siberia and Amazonia, and we develop and apply numerical models to quantify the large-scale sources and sinks of the greenhouse gases.
