Measurements are the sole judge of scientific truth and provide access to unpredictable information, enabling the characterization and monitoring of complex terrestrial systems. Based on lectures and field- and laboratory training, the students learn to apply modern methods to determine forest inventory parameters and to measure subsurface properties and processes.
Learning objective
The students will be able to: - explain measurement principles that are used for characterization of landscapes and terrestrial systems - select appropriate measurement methods and sampling design to quantify key variables and processes above ground and in the subsurface - deploy sensors in the field - interpret collected laboratory and field data and report main conclusions deduced from measurements
