Using a Large‐n Seismic Array to Explore the Robustness of Spectral Estimations
(Geophysical Research Letters, 2020-10-31)Spectral analysis is widely used to estimate and refine earthquake source parameters such as source radius, seismic moment, and stress drop. This study aims to quantify the precision of the single spectra and empirical ... -
Using Clustering, Statistical Modeling, and Climate Change Projections to Analyze Recent and Future Region‐Specific Compound Ozone and Temperature Burden Over Europe
(GeoHealth, 2022-04-16)High ground‐level ozone concentrations and high air temperatures present two health‐relevant natural hazards. The most severe health outcomes are generally associated with concurrent elevated levels of both variables, ... -
Using Principal Component Analysis of Satellite and Ground Magnetic Data to Model the Equatorial Electrojet and Derive Its Tidal Composition
(Journal of Geophysical Research: Space Physics, 2022-09-25)The intensity of the equatorial electrojet (EEJ) shows temporal and spatial variability that is not yet fully understood nor accurately modeled. Atmospheric solar tides are among the main drivers of this variability but ... -
Using quantum optical sensors for determining the Earth’s gravity field from space
(Journal of Geodesy, 2020-07-24)Quantum optical technology provides an opportunity to develop new kinds of gravity sensors and to enable novel measurement concepts for gravimetry. Two candidates are considered in this study: the cold atom interferometry ... -
Using seasonal rainfall clusters to explain the interannual variability of the rain belt over the Greater Horn of Africa
(International Journal of Climatology, 2020)The seasonal cycle of rainfall over the Greater Horn of Africa (GHA) is dominated by the latitudinal migration and activity of the tropical rain belt (TRB). The TRB exhibits high interannual variability in the GHA and the ... -
Using Thermal Springs to Quantify Deep Groundwater Flow and Its Thermal Footprint in the Alps and a Comparison With North American Orogens
(Geophysical Research Letters, 2020-11-21)Deep groundwater flow in mountain belts and its thermal effects are uncertain. Here, we use a new database of discharge, temperature, and composition of thermal springs in the Alps to estimate the extent of deep groundwater ... -
Validation and calibration of coupled porous-medium and free-flow problems using pore-scale resolved models
(Computational Geosciences, 2020-09-05)The correct choice of interface conditions and effective parameters for coupled macroscale free-flow and porous-medium models is crucial for a complete mathematical description of the problem under consideration and for ... -
Validation of the Aeolus L2B Rayleigh winds and ECMWF short‐range forecasts in the upper troposphere and lower stratosphere using Loon super pressure balloon observations
(Quarterly Journal of the Royal Meteorological Society, 2022-11-08)The novel Aeolus satellite, which carries the first Doppler wind lidar providing profiles of horizontal line‐of‐sight (HLOS) winds, addresses a significant gap in direct wind observations in the global observing system. ... -
Variability of the Indian Monsoon in the Andaman Sea Across the Miocene-Pliocene Transition
(Paleoceanography and Paleoclimatology, 2020)We reconstructed the variability of the Earth's strongest hydrological system, the Indian monsoon, over the interval 6.24 to 4.91 Ma at International Ocean Discovery Program (IODP) Expedition 353 Site U1448 in the Andaman ... -
Variability of the precipitation over the Tianshan Mountains, Central Asia. Part I: Linear and nonlinear trends of the annual and seasonal precipitation
(International Journal of Climatology, 2021-06-21)The Tianshan Mountains, with their status as ‘water tower’, receive quantities of precipitation that are among the highest in Central Asia. There are considerable knowledge gaps regarding the understanding of spatial and ... -
Variation of Fault Creep Along the Overdue Istanbul‐Marmara Seismic Gap in NW Türkiye
(Geophysical Research Letters, 2023-03-22)Strain energy from tectonic loading can be partly released through aseismic creep. Earthquake repeaters, repeatedly activated brittle fault patches surrounded by creep, indicate steady‐state creep that affects the amount ... -
