1001 Rocket Launches for Space Missions and Their Infrasonic Signature
(Geophysical Research Letters, 2021-04-28)Infrasound array processing is applied to monitor and characterize atmospheric explosions in the context of the Comprehensive Nuclear‐Test‐Ban Treaty. Anyhow, for many infrasound sources the exact location and time are ... -
3D Active Source Seismic Imaging of the Alpine Fault Zone and the Whataroa Glacial Valley in New Zealand
(Journal of Geophysical Research: Solid Earth, 2021-12-04)The Alpine Fault zone in New Zealand marks a major transpressional plate boundary that is late in its typical earthquake cycle. Understanding the subsurface structures is crucial to understand the tectonic processes taking ... -
3D Classified GPR Facies Models From Multi-Frequency Data Volumes: A Synthetic Study
(2022)Modern GPR systems allow for acquiring densely sampled data sets also using different antenna frequencies. Here, we consider such a multi-frequency approach to image near-surface sedimentary structures at different spatial ... -
3D Local Earthquake Tomography of the Ecuadorian Margin in the Source Area of the 2016 Mw 7.8 Pedernales Earthquake
(Journal of Geophysical Research: Solid Earth, 2021-03-25)Based on manually analyzed waveforms recorded by the permanent Ecuadorian network and our large aftershock deployment installed after the Pedernales earthquake, we derive three‐dimensional Vp and Vp/Vs structures and ... -
3D Reconstruction of Bridges from Airborne Laser Scanning Data and Cadastral Footprints
(Journal of Geovisualization and Spatial Analysis, 2021-04-12)The given paper describes a method for automatic 3D reconstruction of bridges from cadastral footprints and airborne laser scanning point clouds. The reconstructed bridges are used to enrich 3D city models. Unlike roofs, ... -
3‐D Modeling of Vertical Gravity Gradients and the Delimitation of Tectonic Boundaries: The Caribbean Oceanic Domain as a Case Study
(Geochemistry, Geophysics, Geosystems, 2019-11-28)Geophysical data acquisition in oceanic domains is challenging, implying measurements with low and/or nonhomogeneous spatial resolution. The evolution of satellite gravimetry and altimetry techniques allows testing 3‐D ... -
4D quantification of alpine permafrost degradation in steep rock walls using a laboratory‐calibrated electrical resistivity tomography approach
(Near Surface Geophysics, 2021-03-09)The warming of rock permafrost affects mechanical stability and hydro‐cryostatic pressures in rock walls. The coincident decrease in slope stability frequently affects infrastructure by creep and subsidence and promotes ... -

A Binomial Stochastic Framework for Efficiently Modeling Discrete Statistics of Convective Populations
(Journal of Advances in Modeling Earth Systems, 2021-03-23)Understanding the coupling between convective clouds and the general circulation, as well as addressing the gray zone problem in convective parameterization, requires insight into the genesis and maintenance of spatial ... -
A cold pool perturbation scheme to improve convective initiation in convection‐permitting models
(Quarterly Journal of the Royal Meteorological Society, 2021-05-04)Cold pools originate from evaporation in precipitating downdraughts and spread as density currents at the surface. Vertical motion at the leading edge of the cold pool is an important trigger for new convective cells in ... -
A Combined Neural Network‐ and Physics‐Based Approach for Modeling Plasmasphere Dynamics
(Journal of Geophysical Research: Space Physics, 2021-03-16)In recent years, feedforward neural networks (NNs) have been successfully applied to reconstruct global plasmasphere dynamics in the equatorial plane. These neural network‐based models capture the large‐scale dynamics of ... -
A comparison of Bayesian hierarchical space-time models for earthquake data
(2004)Stochastic earthquake models are often based on a marked point process approach as for instance presented in Vere-Jones (1995). This gives a fine resolution both in space and time making it possible to represent each ... -
A Comparison of Radial Diffusion Coefficients in 1‐D and 3‐D Long‐Term Radiation Belt Simulations
(Journal of Geophysical Research: Space Physics, 2021-08-13)Radial diffusion is one of the dominant physical mechanisms driving acceleration and loss of radiation belt electrons. A number of parameterizations for radial diffusion coefficients have been developed, each differing in ... -
A Comparison of the Location of the Mid‐Latitude Trough and Plasmapause Boundary
(Journal of Geophysical Research: Space Physics, 2021-04-15)Abstract: We have compared the location of the mid‐latitude trough observed in two dimensional vertical total electron content (vTEC) maps with four plasmapause boundary models, Radiation Belt Storm Probes (RBSP) observations, ... -
A comprehensive model of seismic velocities for the Bay of Mecklenburg (Baltic Sea) at the North German Basin margin: implications for basin development
(Geo-Marine Letters, 2021-04-15)The geometry of sedimentary basins is normally described by the interpretation of seismic reflectors. In addition to that, rock properties of the sedimentary successions between these reflectors give further insight into ... -
A Comprehensive Study of Infrasound Signals Detected from the Ingolstadt, Germany, Explosion of 1 September 2018
