Lecture Series (no longer running)

In the TR32 Lecture Series, the diverse themes of the research carried out within the collaborative research centre were introduced by the principal investigators. The lectures were primarily organised for the doctoral students who are members of TR32's Integrated Research Training Group (IRTG), but they were open to all.

In summer 2013, the Lecture Series was replaced by Research Training Days: full-day training events on TR32-related topics.

Hendrik Elbern

Data assimilation principles

Data assimilation combines all available information from observations, remote sensing measurements, the model, and other statistical data, to produce an optimally estimated "analysis", preferably with error bars.
The lecture will provide first motivation and fundamental basics of data assimilation, the meaning of "optimal", the relation to Inverse Modelling, and then an overview of popular approaches.
Finally, a view on today's state-of-the-art four-dimensional variational approach, the ensemble Kalman filter will be given.
The presentation aims to serve as a help for identifying the suitable data assimilation algorithm for own purposes.

Harrie-Jan Hendricks Franssen

Data assimilation in hydrology

The second hour will focus on data assimilation methods in hydrology. The main uncertainties that affect hydrological predictions will be listed and discussed and it will be clarified how (sequential) data assimilation methods are therefore adapted to optimally handle these uncertainty sources.

A focus will be on parameter estimation in the context of sequential data assimilation methods. Also a few examples will be given.

Geoinformatics (Lecture and discussion)

The core idea of the presentation is to introduce (i) the definition of Geoinformatics, (ii) basic concepts, and (iii) all day applications. Additionally, ongoing project activities (e.g. TR32DB) will be explained as case studies.

Environmental monitoring (Lecture and discussion)

In the presentation the environmental monitoring concept of the TERENO will be described. The Wüstebach research station is taken as an example to illustrate the potential of intensive hydrologic monitoring for process analysis at the subcatchment scale.

Michael Herbst


The first lecture is focused on basic multivariate geostatistics. Three major problem areas of geostatistics will be addressed: quantifying spatial variability (variograms), multivariate spatial interpolation (kriging), and stochastic simulation.
for presentation: see TR32DB
Basic literature is available from m.herbst@fz-juelich.de

Bernd Diekkrüger

Patterns in Hydrology

The second lecture will focus on patterns, processes and functions in catchment hydrology. Besides description, analysis and modelling of patterns, scale dependencies in space and time will be discussed.

Large eddy modeling of atmosphere and land surface interaction

This lecture provides a general description of turbulence and turbulent transfer. The turbulent kinetic energy equation and the turbulent energy spectrum will be explained. The concept of large eddy and large eddy modeling will be introduced. Examples of large eddy modeling will be given.

for presentation: see TR32DB


Jan Vanderborght

Inverse Modelling

In this lecture I will briefly give the concept of inverse modelling, the definition of an objective function, multi-objective versus single objective optimisation, and local versus global optimisation. After introducing the concepts and definitions, an often used local optimisation procedure and its similarities with linear regression will be presented. Finally, the uncertainty of the inversely estimated parameters will be discussed.

Uwe Rascher
Photosynthesis: from light to biomass, part 1

This lecture introduces some of the phenomena that lie at the basis of photosynthesis: light as an electromagnetic wave; light absorption in plant pigments; charge separation in the photosystem and provision of enery-rich chemical bonds. Methodological hyperspectral and fluorescence techniques are introduced and their potential to quantify the functional status of photosynthetic charge separation is discussed.

for presentation: see TR32DB


Frank Ewert
Photosynthesis: from light to biomass, part 2

This lecture concentrates on carbon dioxide fixation, evaporation, biomass allocation and respiration. Further, photosynthesis at the leaf vs. the canopy level and biomass prediction models are addressed.

09:30 Lutz Weihermüller
Theory of flow of water in soils
This lecture covers the principles of water flow in soils. We will briefly cover: soil as a three-phase system, capillarity and matric potential, saturated and unsaturated flow equation, and parameterization of unsaturated flow models.
for presentation: see TR32DB
    10:30 Sander Huisman
Soil hydrological measurements for unsaturated water flow
This lecture discusses the toolkit of a vadose zone hydrologist for investigating unsaturated flow. We will briefly discuss the measurement principle of tensiometers and common soil water content sensors. The limitations of these local scale measurements will be discussed, and the need for alternative measurement strategies will be made clear. Next, remote sensing, wireless sensor networks, cosmic ray neutron probes and hydrogeophysical measurements will be briefly introduced and the potential and drawbacks to investigate unsaturated water flow will be discussed.

An Introduction to TR32: Soil-Vegetation-Atmosphere Systems

Transregional Collaborative Research Centre 32 "Patterns in Soil-Vegetation-Atmosphere-Systems: Monitoring, Modelling and Data Assimilation" was initiated in 2007. Its main hypothesis is that a better understanding of the exchange mechanisms between the different compartments of the Earth system can be gained from pattern analysis. This lecture provides an overview of the main achievements and conclusions of the first funding phase and looks ahead to the main research questions and challenges for the second funding phase, which started at the beginning of 2011.

Stefan Kollet
Simulation of terrestrial systems

Simulation of terrestrial systems involves the understanding and mathematical representation of the coupled mass, energy and momentum balances from the subsurface across the land surface into the atmosphere and vice versa. The objective is to treat the terrestrial system in an integrated fashion instead of simulating each compartment (e.g., the subsurface and atmosphere) separately. In this endeavor, we are facing natural interfaces, which are characterized by complex physical and chemical processes that must be accounted for in the simulations. Starting in the subsurface, we will take a journey and will work our way up toward the atmosphere traversing interfaces, such as the free groundwater table; the interface between groundwater and surface water; and the land surface with turbulent transfer of mass, energy and momentum into the lower atmosphere. Along our way, we will learn about the basic theoretical concepts of simulating the terrestrial system in an integrated fashion and, maybe even more important, we will gain understanding of the major simplifying assumptions and uncertainties involved.
