Core course: Atmosphere & Ocean
IMPRS-gBGC core courses introduce PhD students 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.

|8:30-8:50||B0.002||L||Overview of the module: goals, expectations|
|8:50-9:30||B0.002||L||Introduction to the climate system: atmosphere, ocean, land, ice, interior, structure, composition, global biogeochemical cycles, human activity and global change|
|9:30-11:00||B0.002||L, P||Atmospheric basics: forms of energy and energy transfer, first and second law of thermodynamics, ideal gas law, hydrostatic balance, lapse rate, barometric equation, Carnot efficiency, maximum work|
|14:00-14:45||B0.002||L, P||Radiative forcing: basic radiation laws, radiative temperature, variations in solar radiation, greenhouse effect|
|14:45-15:30||B0.002||L, P||Planetary energy balance: components of the global energy balance, atmospheric heat transport, planetary comparison|
|15:45-16:30||B0.002||L, P||Biogeochemical cycles: global cycles, residence times, geology and biogeochemical cycles, evolution of atmospheric composition|
|16:30-17:00||B0.002||Wrap-up: summary, next steps, feedback|
|Tue||Radiation||Dietrich Feist, Julia Marshall|
|9:00-12:00||B0.002||L, P||Absorption by atmospheric gases||Dietrich Feist|
|14:00-15:30||B0.002||L||Attenuation by other atmospheric constituents||Julia Marshall|
|15:30-17:00||B0.002||P||Exercises with a 1-D radiation model|
Using an online version of a real one-dimensional radiative transfer model, various experiments will be undertaken. This will allow one to 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. It should provide the students with a better feeling of what 1 W/m2 means.
|Wed||Dynamics||Christoph Gerbig, Christian Roedenbeck|
|9:00-10:30||C1.011||L||Motion in atmosphere and ocean, hydrologic cycle||Christoph Gerbig|
|11:00-12:30||C1.011||L||Numerical transport modeling||Christian Rödenbeck|
|14:00-17:00||C1.011||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.
