Measurement technology
Head of the working group:
Dr. Ronald Queck
Working focus
- Combination and merging of measurements on different space and time scales including the intersection of ground-based measurements and remote sensing
- Further development and improvement of measurement methods and techniques such as eddy covariance, turbulence measurements, acoustic tomography, etc.
- Quantification and balancing of unavoidable measurement uncertainties and analysis of their effect in different space and time scales
- Conception, construction and realization of special sensors adapted to the measurement task as well as development and setup of suitable data acquisition systems
- development and testing of suitable methods for signal processing, measurement data processing and time series analysis
current projects connected with the working group
(detailed information about the project content can be found on the individual project pages)
- MEDIWA Interception (localization of water storage and evapotranspiration in forest stands)
- ICOS (BMBF, subproject management Prof. Dr. Christian Bernhofer, Dr. Thomas Grünwald)
- TREGATA (greenhouse gases from dams)
further current activities
- Thermography: area-based high-frequency temperature measurements for testing and improving measurement configurations
- Measurement backpack: mobile measurement of meteorological variables to determine the spatial variability of the microclimate (e.g. urban climate), connection with a stationary measurement to correct the diurnal variation of the meteorological variables
- Development of radiation sensors
- Development of "mini climate stations" on the basis of RaspBerry Pi
