Understanding Micropolar Theory in the Earth Sciences I: The Eigenfrequency ωr
(
- Pure and Applied Geophysics
, 2021-12-25)
Even though micropolar theories are widely applied for engineering applications such as the design of metamaterials, applications in the study of the Earth’s interior still remain limited and in particular in seismology. ...
Minimal Recipes for Global Cloudiness
(
- Geophysical Research Letters
, 2022-10-26)
Clouds are primary modulators of Earth's energy balance. It is thus important to understand the links connecting variabilities in cloudiness to variabilities in other state variables of the climate system, and also describe ...
Precipitation Over Southern Africa: Moisture Sources and Isotopic Composition
(
- Journal of Geophysical Research: Atmospheres
, 2022-11-03)
Southern Africa, with its vast arid to semiarid areas, is considered vulnerable to precipitation changes and amplifying weather extremes. However, during the last 100 ka, huge lakes existed in the currently dry central ...
Impact of Parametrizing Microphysical Processes in the Jet and Vortex Phase on Contrail Cirrus Properties and Radiative Forcing
(
- Journal of Geophysical Research: Atmospheres
, 2022-12-07)
Contrail ice nucleation and ice crystal loss during the vortex phase control ice crystal numbers in young contrails and can have a strong impact on the properties and the life cycle of contrail cirrus. For current soot ...
Timing and Origin of Compressional Tectonism in Mare Tranquillitatis
(
- Journal of Geophysical Research: Planets
, 2023-02-05)
The lithosphere of the Moon has been deformed by tectonic processes for at least 4 billion years, resulting in a variety of tectonic surface features. Extensional large lunar graben formed during an early phase of net ...
Enhanced solar radiation pressure model for GPS satellites considering various physical effects
(
- GPS Solutions
, 2021-01-28)
Solar radiation pressure (SRP) is the dominant non-gravitational perturbation for GPS satellites. In the IGS (International GNSS Service), this perturbation is modeled differently by individual analysis centers (ACs). The ...
Performance assessment of GNSS-based real-time navigation for the Sentinel-6 spacecraft
(
- GPS Solutions
, 2021-11-15)
The feasibility of precise real-time orbit determination of low earth orbit satellites using onboard GNSS observations is assessed using six months of flight data from the Sentinel-6A mission. Based on offline processing ...
Middle Miocene Climate and Stable Oxygen Isotopes in Europe Based on Numerical Modeling
(
- Paleoceanography and Paleoclimatology
, 2022-10-24)
The Middle Miocene (15.99–11.65 Ma) of Europe witnessed major climatic, environmental, and vegetational change, yet we are lacking detailed reconstructions of Middle Miocene temperature and precipitation patterns over ...
Projected Impact of Increased Global Warming on Heat Stress and Exposed Population Over Africa
(
- Earth's Future
, 2023-01-11)
This study investigates the impact of increased global warming on heat stress changes and the potential number of people exposed to heat risks over Africa. For this purpose a heat index has been computed based on an ...
Seismic and Tsunamigenic Characteristics of a Multimodal Rupture of Rapid and Slow Stages: The Example of the Complex 12 August 2021 South Sandwich Earthquake
(
- Journal of Geophysical Research: Solid Earth
, 2022-11-07)
On 12 August 2021, a >220 s lasting complex earthquake with M<sub>w</sub> > 8.2 hit the South Sandwich Trench. Due to its remote location and short interevent times, reported earthquake parameters varied significantly ...
