Funktion und Aufgaben:

Senior scientist in Section 'Hydrology'
Head of the Working Group ' Hydrogravimetry and large-scale hydrology'
Professor for Hydrogravimetry at Potsdam University (Institute of Environmental Science and Geography)

ResearcherID C-9892-2011
ORCID 0000-0001-6233-8478

Wissenschaftliche Interessen:

• Understanding water storage variations in space and time, from surface water bodies to the vadose zone and the groundwater
• Developing geodetic/geophysical monitoring techniques for hydrological applications, in particular
  - satellite gravimetry
  - terrestrial gravimetry
  - Cosmic Ray Neutron Sensing (CRNS) for soil moisture monitoring
  - GNSS reflectometry for surface soil moisture and snow monitoring
• Satellite gravimetry (GRACE, GRACE-FollowOn, GRACE-C and upcoming missions) for the assessment of large-scale water storage changes
• Terrestrial gravimetry for assessing field-scale water storage variations (with superconducting gravimeters, absolute quantum gravimeters, and/or spring gravimeters in field applications) (e.g., Güntner et al. 2017; 2024)
  
• Integration of monitoring data with hydrological models, multi-critierial calibration (in particular for the WaterGAP Global Hydrology Model (WGHM))
• Installation and operation of hydrological and hydro-gravimetric observatories and monitoring systems (e.g., TERENO-Northeast, Wettzell, SAGOS, AGGO, MOSES)
