Seismic Full‐Waveform Inversion of the Crust‐Mantle Structure Beneath China and Adjacent Regions
(
- Journal of Geophysical Research: Solid Earth
, 2022-09-19)
We present the first‐generation full‐waveform tomographic model (SinoScope 1.0) for the crust‐mantle structure beneath China and adjacent regions. The three‐component seismograms from 410 earthquakes recorded at 2,427 ...
Observational Evidence for Multivariate Drought Hazard Amplifications Across Disparate Climate Regimes
(
- Earth's Future
, 2022-09-16)
Drought poses significant challenges to global water security in a warming world. A global‐scale synthesis of the multivariate drought risk considering interdependencies between drought attributes across disparate climate ...
Determining the Origin of Tidal Oscillations in the Ionospheric Transition Region With EISCAT Radar and Global Simulation Data
(
- Journal of Geophysical Research: Space Physics
, 2022-09-30)
At high‐latitudes, diurnal and semidiurnal variations of temperature and neutral wind velocity can originate both in the lower atmosphere (UV or infrared absorption) and in the thermosphere‐ionosphere (ion convection, EUV ...
Teleconnection Patterns of Different El Niño Types Revealed by Climate Network Curvature
(
- Geophysical Research Letters
, 2022-09-09)
The diversity of El Niño events is commonly described by two distinct flavors, the Eastern Pacific (EP) and Central Pacific (CP) type. While the remote impacts, that is, teleconnections, of EP and CP events have been studied ...
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 ...
Combination Strategy for the Geocentric Realization of Regional Epoch Reference Frames
(
- Journal of Geophysical Research: Solid Earth
, 2022-10-25)
For high‐resolution regional geodetic applications, the International Terrestrial Reference Frame (ITRF) is complemented by regional densifications. These are realized either as multi‐year solutions related to a tectonic ...
Dissolved gases in the deep North Atlantic track ocean ventilation processes
(
- Proceedings of the National Academy of Sciences
, 2023)
Gas exchange between the atmosphere and ocean interior profoundly impacts global climate and biogeochemistry. However, our understanding of the relevant physical processes remains limited by a scarcity of direct observations. ...
An ambitious new mission seeks the origin of the moons of Mars
(
- Proceedings of the National Academy of Sciences
, 2023)
Two mysterious moons whirl around Mars. Despite the many missions to the planet, not a single one has focused on its satellites — or, rather, not a single successful one. Three previous Martian moon explorers, launched by ...
Realistische 3D-Simulation von Georadar-Daten im sedimentologischen Kontext
(2019)
In der Geophysik stellt die Modellierung synthetischer Referenzdatensätze eine wichtige
Grundlage sowohl für die Evaluation grundlegender Schritte der Datenbearbeitung als
auch für die Entwicklung neuartiger Ansätze zur ...
Estimating moisture changes in concrete using GPR velocity analysis: potential and limitations
(2018)
Chloride-induced corrosion of steel rebars is a key problem
for the durability and safety of reinforced concrete buildings
such as bridges. Penetrating rainwater transports the
chlorides into exposed parts of these ...
