Core course: Atmosphere & Ocean

1. Concept

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.

2. Preparation

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.

Time	Where	Type	Content	Who
Mon			Basics	Axel Kleidon
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 black body radiation and the electromagnetic spectrum molecular absorption lines of major constituents of the atmosphere absorption coefficient and opacity continuous and discrete radiative transfer equation solar and earth spectra at the ground and the top of the atmosphere excercise on radiative transfer calculations	Dietrich Feist
14:00-15:30	B0.002	L	Attenuation by other atmospheric constituents scattering in the Rayleigh, Mie, and geometric regimes introduction to aerosols and their optical properties direct and indirect radiative effects of aerosols cloud radiative properties multiple scattering	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.	Julia Marshall
Wed			Dynamics	Christoph Gerbig, Christian Roedenbeck
9:00-10:30	C1.011	L	Motion in atmosphere and ocean, hydrologic cycle global circulation of the atmosphere frontal systems basics of global ocean circulation hydrologic cycle, clouds	Christoph Gerbig

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.	Christoph Gerbig and Christian Rödenbeck
Thu			Surface exchange	Ute Karstens, Olaf Kolle
9:00-10:30	B0.002	L	Land surface climatology fluxes at the land surface albedo climate feedback biophysical feedback Boundary layer meteorology general characteristics, structure and diurnal cycle atmospheric stability	Ute Karstens
