Temperatures Near the Lunar Poles and Their Correlation With Hydrogen Predicted by LEND
(Journal of Geophysical Research: Planets, 2021-08-30)The lunar polar regions offer permanently shadowed regions (PSRs) representing the only regions which are cold enough for water ice to accumulate on the surface. The Lunar Exploration Neutron Detector (LEND) aboard the ... -
Temporal Modulation of the Local Microseism in the North Sea
(Journal of Geophysical Research: Solid Earth, 2020)Primary and secondary microseism originating in the world oceans and peaking at around 14 and 7 s, respectively, characterize the Earth's background noise in that frequency range. Microseism generated in marginal seas with ... -
Temporal Variations of the Marine Geoid
(Journal of Geophysical Research: Oceans, 2020-11-08)The effects of temporal changes in the marine geoid on estimates of the ocean dynamic topography are being investigated. Influences from mass redistribution due to changes of land hydrology, ice sheets, glacial isostatic ... -
Testing the consistency of Holocene and Last Glacial Maximum spatial correlations in temperature proxy records
(Journal of Quaternary Science, 2020)Holocene temperature proxy records are commonly used in quantitative synthesis and model-data comparisons. However, comparing correlations between time series from records collected in proximity to one another with the ... -
The 12 December 2017 Baumgarten Gas Hub Explosion: A Case Study on Understanding the Occurrence of a Large Infrasound Azimuth Residual and a Lack of Seismic Observations
(Pure and Applied Geophysics, 2020-07-27)The Baumgarten explosion occurred on 12 December 2017 at a gas storage site about 30 km east of Vienna, Austria. Acoustic arrivals from this accidental surface explosion were detected at dozens of stations of the AlpArray ... -
The 1994 Piedmont flood: an archetype of extreme precipitation events in Northern Italy
(Bulletin of Atmospheric Science and Technology, 2020-09-01)Extreme precipitation events (EPEs) are meteorological phenomena of major concern for the densely populated regions of northern and central Italy. Although statistically rare, they tend to be recurrent in autumn and share ... -
The 2018–2020 Multi‐Year Drought Sets a New Benchmark in Europe
(Earth's Future, 2022-03-24)During the period 2018–2020, Europe experienced a series of hot and dry weather conditions with significant socioeconomic and environmental consequences. Yet, the extremity of these multi‐year dry conditions is not recognized. ... -
The application of reproducing kernel based spline approximation to seismic surface and body wave tomography - theoretical aspects and numerical results
(Univ. Kaiserslautern, 2007)The main aim of this work was to obtain an approximate solution of the seismic traveltime tomography problems with the help of splines based on reproducing kernel Sobolev spaces. In order to be able to apply the spline ... -
The Arctic Ocean in CMIP6 Models: Biases and Projected Changes in Temperature and Salinity
(Earth's Future, 2022-02-11)We examine the historical evolution and projected changes in the hydrography of the deep basin of the Arctic Ocean in 23 climate models participating in the Coupled Model Intercomparison Project Phase 6 (CMIP6). The ... -
The Arctic Polar Vortex Response to Volcanic Forcing of Different Strengths
(Journal of Geophysical Research: Atmospheres, 2021-06-01)Tropical volcanic eruptions injecting sulfur into the stratosphere are assumed to not only scatter radiation and cool Earth's surface but also alter atmospheric circulation and in particular to strengthen the stratospheric ... -
The Boulder Population of Asteroid 4 Vesta: Size‐Frequency Distribution and Survival Time
(Earth and Space Science, 2021-01-26)Dawn's framing camera observed boulders on the surface of Vesta when the spacecraftwas in its lowest orbit (Low Altitude Mapping Orbit, LAMO). We identified, measured, and mapped boulders in LAMO images, which have a scale ... -
The central parsec of the milky way at 3.8 micrometer
(Univ. Köln, 2008)The central part of the Milky Way is a unique environment where an interplay of different astrophysical phenomena can be studied, starting from the physics of the interstellar medium, stellar physics and star formation, ... -
The Climatology of Elevated Stratopause Events in the UA‐ICON Model and the Contribution of Gravity Waves
(Journal of Geophysical Research: Atmospheres, 2023-04-09)The climatologies of the stratopause height and temperature in the UA‐ICON model are examined by comparing them to 17‐years (2005–2021) of Microwave Limb Sounder (MLS) observations. In addition, the elevated stratopause ... -
The combined global gravity field model XGM2019e
(Journal of Geodesy, 2020-07-20)XGM2019e is a combined global gravity field model represented by spheroidal harmonics up to degree and order (d/o) 5399, corresponding to a spatial resolution of 2′ (~ 4 km). As data sources, it includes the satellite model ... -
The Contribution of Sprite Streamers to the Chemical Composition of the Mesosphere-Lower Thermosphere
(Geophysical Research Letters, 2020)Sprites are mesospheric filamentary discharges that liberate and accelerate large quantities of electrons. They produce local enhancements of some chemical species and fast (millisecond) optical emissions. In this work, ... -
The Delayed Ionospheric Response to the 27‐day Solar Rotation Period Analyzed With GOLD and IGS TEC Data
