1.  General information

Date: March 15 - 19, 2021
Location: webinar
Teacher: Martin Heimann
Category: Courses related to BGC cycles - Overview course
0.2 CP per course day

Goal of the module is an overview over the global Earth System, its major components (Atmosphere, ocean, land surfaces and cryosphere), their interactions through exchanges of energy, momentum and materials, and the major physical, chemical and biological processes controlling these exchanges. A special emphasis is given to the role of the global cycles of biogeochemical elements and their modifications in the context of global change.

2.  Prerequisites

Please indicate in the registration form if you can bring a laptop to the course (for the practical part). You will need the Wolfram Mathematica CDF Player and a web browser. Alternatively, you need on your laptop a working version of Python 3 accessible through Jupyter notebooks. An installable version of the Mathematica CDF Player for Windows and for MacOS is available on the OwnCloud course website (see below). If you do not have a laptop available, we can lend you one if we know early enough.

3.  Course materials

will be posted always after the lectures in nextcloud.

1 During the course a few Earth System science questions will be posed, which the participants are asked to work on in groups during the the course. Each group will present the context of the question, the approach in trying to answer it and the results during the session on a separate day (tba). More details will be announced in the course.
