- * 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.

+++ Collaboration with Max-Planck Partner Group in India +++
December, 2018

Dhanya Pillai from the Indian Institute of Science Education and Research (IISER) in Bhopal, is visiting our department for two weeks in December. She heads a Max-Planck Partner Group entitled "Top-down estimation of regional sources and sinks of greenhouse gases over the Indian subcontinent constrained by atmospheric observations and modeling". During her stay she will be working with Julia Marshall and Christoph Gerbig on setting up inverse modelling tools at the mesoscale for the indian domain. A further topic will be the development of remote sensing based estimates of emissions from agricultural burning, which represents a major problem for large regions of India.

+++ Institute’s representative for the Max Planck PhDNet +++
November, 2018

This Summer Martijn Pallandt has been elected as the institute’s representative for the Max Planck PhDNet (PhDnet). PhDnet is a platform for exchange among the about 5000 PhD candidates working at 83 Max Planck Institutes. The goal of PhDnet is to bring together PhD’s from all these institutes to improve interdisciplinary cooperation, optimize doctoral education, scientific exchange, and strengthen academic solidarity.

+++ Finished PhD +++
17 October, 2018

Sabrina Arnold successfully defended her thesis 'Ground-based Remote Sensing of Carbon Dioxide, Carbon Monoxide and Methane on Ascension Island Using Fourier Transform Infrared Spectroscopy' at the University of Bremen.
