Alternating North‐South Brightness Ratio of Ganymede's Auroral Ovals: Hubble Space Telescope Observations Around the Juno PJ34 Flyby
(
- Geophysical Research Letters
, 2022-12-12)
We report results of Hubble Space Telescope observations from Ganymede's orbitally trailing side which were taken around the flyby of the Juno spacecraft on 7 June 2021. We find that Ganymede's northern and southern auroral ...

Multi-criteria modelling of drought: a study of Brandenburg Federal State, Germany
(
- Modeling Earth Systems and Environment
, 2021-06-13)
Drought is the absence or below-required supply of precipitation, runoff and or moisture for an extended time period. Modelling drought is relevant in assessing drought incidence and pattern. This study aimed to model the ...
On the Ridging of the South Atlantic Anticyclone Over South Africa: The Impact of Rossby Wave Breaking and of Climate Change
(
- Geophysical Research Letters
, 2022-10-19)
Ridging South Atlantic Anticyclones contribute an important amount of precipitation over South Africa. Here, we use a global coupled climate model and the ERA5 reanalysis to separate for the first time ridging highs (RHs) ...
Return to rapid ice loss in Greenland and record loss in 2019 detected by the GRACE-FO satellites
(
- Communications Earth & Environment
, 2020-08-20)
Between 2003-2016, the Greenland ice sheet (GrIS) was one of the largest contributors to sea level rise, as it lost about 255 Gt of ice per year. This mass loss slowed in 2017 and 2018 to about 100 Gt yr<sup>−1</sup>. Here ...
Characteristics of the Matuyama‐Brunhes Magnetic Field Reversal Based on a Global Data Compilation
(
- Journal of Geophysical Research: Solid Earth
, 2023-02-01)
Magnetic field reversals are irregular events in Earth's history when the geomagnetic field changes its polarity. Reversals are recorded by spot and continuous remanent magnetization data collected from lava flows and ...
Direct measurements of atomic oxygen in the mesosphere and lower thermosphere using terahertz heterodyne spectroscopy
(
- Communications Earth & Environment
, 2021-01-26)
Atomic oxygen is a main component of the mesosphere and lower thermosphere of the Earth, where it governs photochemistry and energy balance and is a tracer for dynamical motions. However, its concentration is extremely ...
Horizontal Correlation Functions of Wind Fluctuations in the Mesosphere and Lower Thermosphere
(
- Journal of Geophysical Research: Atmospheres
, 2023-03-14)
Measurements of kinetic energy in vortical and divergent fluctuations in the mesosphere and lower thermosphere can be used to study stratified turbulence (ST) and gravity waves. This can be done using horizontal correlation ...
Spectral decomposition of the Engineering Strong Motion (ESM) flat file: regional attenuation, source scaling and Arias stress drop
(
- Bulletin of Earthquake Engineering
, 2020-02-01)
We perform a spectral decomposition of the Fourier amplitude spectra disseminated along with the Engineering Strong Motion (ESM) flat file for Europe and Middle East. We apply a non-parametric inversion schema to isolate ...
Regional broad-band ground-shaking modelling over extended and thick sedimentary basins: an example from the Lower Rhine Embayment (Germany)
(
- Bulletin of Earthquake Engineering
, 2020-11-16)
The simulation of broad-band (0.1 to 10 + Hz) ground-shaking over deep and spatially extended sedimentary basins at regional scales is challenging. We evaluate the ground-shaking of a potential M 6.5 earthquake in the ...
