Influence of Volatiles on Mass Wasting Processes on Vesta and Ceres
(Journal of Geophysical Research: Planets, 2021-03-19)We have analyzed mass wasting features, their distribution and deposit geometry on the two largest main asteroid belt objects—protoplanet Vesta and dwarf planet Ceres—and compared their geomorphology and mobility. Both ... -
Inherent Dissipation of Upwind‐Biased Potential Temperature Advection and its Feedback on Model Dynamics
(Journal of Advances in Modeling Earth Systems, 2021-03-19)Higher order upwind‐biased advection schemes are often used for potential temperature advection in dynamical cores of atmospheric models. The inherent diffusive and antidiffusive fluxes are interpreted here as the effect ... -
Initial Response of Nightside Auroral Currents to a Sudden Commencement: Observations of Electrojet and Substorm Onset
(Journal of Geophysical Research: Space Physics, 2022-04-06)Storm sudden commencements (SSC) often precede geomagnetic storms. Commonly, it takes some hours from the step‐like change that marks the SSC to the start of the magnetic storm activity. In a subset of cases, however, ... -
Injection‐Induced Seismic Moment Release and Laboratory Fault Slip: Implications for Fluid‐Induced Seismicity
(Geophysical Research Letters, 2020-11-19)Understanding the relation between injection‐induced seismic moment release and operational parameters is crucial for early identification of possible seismic hazards associated with fluid‐injection projects. We conducted ... -
Insights from recent gravity satellite missions in the density structure of continental margins – With focus on the passive margins of the South Atlantic
(Gondwana Research, 2017)We focus on new gravity and gravity gradient data sets from modern satellite missions GOCE, GRACE and CHAMP, and their geophysical interpretation at passive continental margins of the South Atlantic. Both sides, South ... -
Insolation and Greenhouse Gas Forcing of the South American Monsoon System Across Three Glacial-Interglacial Cycles
(Geophysical Research Letters, 2020)Precipitation extremes with devastating socioeconomic consequences within the South American Monsoon System (SAMS) are expected to become more frequent in the near future. The complexity in SAMS behavior, however, poses ... -
Instabilitäten und Teilchentransport in stoßfreien astrophysikalischen Plasmen
(Univ. Bochum, 2006)In der vorliegenden Arbeit wird zunächst der Transport von kosmischer Strahlung in der Turbulenz der Heliosphäre untersucht. Dabei werden für verschiedene Turbulenzmodelle aktuelle lineare und nichtlineare Theorien mit ... -
Instrumentelle und auswertemethodische Arbeiten zur Wechselstromgeoelektrik.
(Univ. Berlin, 2007)Im Rahmen verschiedener Drittelmittelprojekte waren vom Autor Wechselstrommessungen bei z.T. sehr kleinen Signal- zu Rauschverhältnissen durchzuführen. In den ariden Messgebieten (Ägypten, Sudan) waren hierfür die schlechten ... -
Integrated Interpretation of Magnetic and ERT Data to Characterize a Landfill in the North-West of Cologne, Germany
(Pure and Applied Geophysics, 2021-05-10)Electrical resistivity tomography (ERT) and ground magnetic surveys were applied to characterize an old uncontrolled landfill in a former exploited sand and gravel quarry in an area to the north-west of the city of Cologne, ... -
Integrated processing of ground- and space-based GPS observations: improving GPS satellite orbits observed with sparse ground networks
(Journal of Geodesy, 2020-10-10)The precise orbit determination (POD) of Global Navigation Satellite System (GNSS) satellites and low Earth orbiters (LEOs) are usually performed independently. It is a potential way to improve the GNSS orbits by integrating ... -
Integration of airborne gravimetry data filtering into residual least-squares collocation: example from the 1 cm geoid experiment
(Journal of Geodesy, 2020-08-03)Low-pass filters are commonly used for the processing of airborne gravity observations. In this paper, for the first time, we include the resulting correlations consistently in the functional and stochastic model of residual ... -

Interannual to millennial-scale variability of River Ammer floods and its relationship with solar forcing
(International Journal of Climatology, 2020)The relationship between River Ammer flood frequency variability, extreme summer climate over Europe, and solar forcing is investigated. First, we used observational data to evaluate extreme weather and climate anomaly ... -
Intercalibration of the Plasma Density Measurements in Earth's Topside Ionosphere
(Journal of Geophysical Research: Space Physics, 2021-10-06)Over the last 20 years, a large number of instruments have provided plasma density measurements in Earth's topside ionosphere. To utilize all of the collected observations for empirical modeling, it is necessary to ensure ... -
Intercomparison of different state-of-the-art formulations of the mass density of humid air
(Bulletin of Atmospheric Science and Technology, 2021-12-17)The differences between one classical and three state-of-the-art formulations of the mass density of humid air were quantified. Here, we present both the calculi for direct determination of the humid-air mass density ... -
Interdecadal Pacific Oscillation Drives Enhanced Greenland Surface Temperature Variability During the Last Glacial Maximum
(Geophysical Research Letters, 2020-12-04)Stable oxygen isotope records from central Greenland suggest disproportionally large long‐term surface air temperature (SAT) variability during the Last Glacial Maximum (LGM) relative to preindustrial times. Large perturbations ... -
Interdecadal Pacific Oscillation in Northern Greenland Dust Concentration Variability During the Last 400 Years
(Geophysical Research Letters, 2022-12-23)Statistical analysis of reanalysis and observed data reveals that high dust surface mass concentration in northern Greenland is associated with a Pacific Decadal Oscillation like pattern in its negative phase in the North ... -
Interiors of Earth-Like Planets and Satellites of the Solar System
(Surveys in Geophysics, 2021-12-14)The Earth-like planets and moons in our solar system have iron-rich cores, silicate mantles, and a basaltic crust. Differentiated icy moons can have a core and a mantle and an outer water–ice layer. Indirect evidence for ... -
Internal characteristics of magnetic clouds and interplanetary coronal mass ejections
(Univ. Braunschweig, 2005)Coronal Mass Ejections (CMEs) are extremely dynamical and huge events in which the solar plasma, initially contained in closed coronal magnetic field lines, is ejected into interplanetary space. When a CME is detected ... -
