IMPRS-gBGC course: Atmosphere, Ocean & Land 2021
Category: Core course
Credit points: 0.2 per course day
Date & Place
January 15 - 22, 2021
start at 9:00 a.m.
IMPRS-gBGC core courses introduce doctoral candidates to scientific fields relevant to global biogeochemical cycles in which they have no deep knowledge yet. The purpose of those courses is to facilitate interdisciplinary communication and collaboration.
Please make sure that a working implementation of X windows system is installed on your laptop before the exercises start. For Windows, this could be Cygwin/X, for Mac OS you could use the X11 app. There is a variety of similar applications available, also for Linux systems.
Legend L = Lecture, P = Practical
|Friday, January 15||Basics||Axel Kleidon|
|Monday, January 18||Dynamics||Christoph Gerbig|
|9:00-10:30||L||Motion in atmosphere and ocean, hydrologic cycle|
|11:00-12:30||L||Numerical transport modeling|
|14:00-17:00||P||Exercises with numerical transport models|
We will use a Lagrangian Dispersion Model (LPDM) and a global Transport Model to see how atmospheric transport and mixing of emissions and biosheric fluxes affects the distribution of CO2 in the atmosphere.
|Wednesday, January 20||Surface exchange||Christoph Gerbig, Olaf Kolle, Tarek El-Madany|
|9:00-10:30||L||Land surface climatology|
Boundary layer meteorology
|11:00-11:45||L||Boundary layer meteorology (cont.)||Christoph Gerbig|
|11:45-12:30||L||Eddy flux measurements, Presentation 1||Olaf Kolle|
|13:45 - 14:30||L||Eddy flux measurements, Presentation 2|
|14:40 - 15:45||P||Group 1: Application of eddy covariance method||Olaf Kolle, Tarek El-Madany|
|15:55 - 17:00||P||Group 2: Application of eddy covariance method||Olaf Kolle, Tarek El-Madany|
|Thursday, January 21||Radiation||Julia Marshall|
|9:00-12:00||L, P||Absorption by atmospheric gases|
|14:00-15:30||L, P||Attenuation by other atmospheric constituents|
|15:30-17:00||P||Further experiments with a 1-D radiation model|
Following the examples introduced in the previous sections, further experiments will be carried out using the 1-D radiative transfer model, working in teams. Within the model we can test the effect of changing the quantity of various greenhouse gases, the aerosol optical depth, the cloud properties, and the surface albedo, among other things. By the end of the day the participants should have a better feeling of what 1 W/m2 means, and the radiative implications of some proposed geoengineering methods and climate feedbacks.
|Friday, January 22||Oceans and Cryosphere||Mathias Goeckede, Fabrice Lacroix|
|09:00-10:30||L||Basic principles on global ocean circulation|
|11:00-13:00||L, P||Global ocean carbon cycle||Fabrice Lacroix|
|14:00-15:30||L||Special role of the Arctic in the climate system||Mathias Goeckede|
