Modules

Prerequisites

Contents

In the lecture measurement techniques and the analysis of the measured data in forests are addressed, such as: • Tree increment cores/ stem discs • Dendrometer • Sap-flux • Porometer • Eddy covariance. In the exercise the knowledge gained in the lecture will be applied in form of weekly exercises, which will be presented by the students and discussed. The exercises need to be solved by the students in form of self organized studies. The exercise consists of two parts: Part 1: Excercises Analysis of tree and climatic data e.g. and in situ measurements Part 2: Field campaign Appling of measurements in the field, installation of different monitoring devices.

Learning outcomes

The module trains basic knowledge regarding measurement techniques for tree parameters and it offers an overview of the varying relationships between climate and tree growth on different temporal levels from annual data (tree-rings) to 30min measurements (Dendrometer). In context with data of photosynthesis measurements, gas exchange measurements from the surface to the atmosphere and other climate data the students get the competence to comprehend and evaluate basic questions and problems how climate change and climatic extremes influence forest ecosystems.

Assessment

1. Weekly exercises, Programming excercises in Python or R (50%) 2. Written exam, 45 min (50%)
