A new method to estimate GPS satellite and receiver differential code biases using a network of LEO satellites
; ; (GPS Solutions, 2021-03-09)
The differential code biases (DCBs) of the global positioning system (GPS) receiver onboard low-Earth orbit (LEO) satellites are commonly estimated by a local spherical symmetry assumption together with the known GPS ... -
A new middle Miocene lineage based on taxonomic revision of the large and rare cricetid-rodent genus Lartetomys
; ; ; (Palaeobiodiversity and Palaeoenvironments, 2021-05-13)
Large-sized cricetid rodents (Cricetodotontini) immigrated to Central Europe at the beginning of the Middle Miocene Climate Transition at ca. 15 My and are thus of great value for biostratigraphic and palaeoecologic purposes. ... -
A New Population of Ultra‐Relativistic Electrons in the Outer Radiation Zone
; ; ; ; ; ; (Journal of Geophysical Research: Space Physics, 2022-05-09)
Van Allen Probes measurements revealed the presence of the most unusual structures in the ultra‐relativistic radiation belts. Detailed modeling, analysis of pitch angle distributions, analysis of the difference between ... -
A new practical and economical technique for the obtention of high quality thin section photographs with the help of a simple optical microscope
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Microscopic study is an indispensable step in the determination of the petrographic characteristics of rocks. In Cameroon just like in most developing countries, simple polarizing microscopes of the 20th Century constitute ... -
A new strategy for aeromagnetic survey merging and application to Greenland
;; ; ; (2022)
Aeromagnetic surveys help us to learn about geology. To achieve good coverage, surveys need to be merged. However, conventional methods introduce long-wavelength bias and cannot handle the individual survey quality. We ... -
A new unfolding method for the MAGIC telescope
(Univ. Dortmund, 2008)The presented thesis describes an unfolding method whose principle is to determine the probability that a certain set of events has a certain range of energy. Unfolding methods are not related to the analyzed data and one ... -
A New Unsupervised Learning Method to Assess Clusters of Temporal Distribution of Rainfall and Their Coherence with Flood Types
; (Water Resources Research, 2020)
Several factors have an impact on the generation of floods, for example, antecedent moisture conditions and the shape of the catchment. A very important factor is the event rainfall, especially its temporal distribution. ... -
A nonlocal three‐dimensional turbulence parameterization (NLT3D) for numerical weather prediction models
; (Quarterly Journal of the Royal Meteorological Society, 2021-10-29)
With increasing resolution of numerical weather prediction (NWP) models, classical subgrid‐scale processes become increasingly resolved on the model grid. In particular, turbulence in the planetary boundary layer (PBL) is ... -
A Note on Aerosol Processing by Droplet Collision‐Coalescence
; (Geophysical Research Letters, 2023-06-01)
Abstract The processing of aerosol by droplet collision‐coalescence is analyzed in three‐dimensional ...

A note on the wedge reversion antisymmetry operation and 51 types of physical quantities in arbitrary dimensions
(Acta Crystallographica Section A, 2023-06-05)The paper by Gopalan [
(2020). Acta Cryst. A76 , ... -
A note on world precipitation during the last glaciation
(E&G – Quaternary Science Journal; Vol.16, No. 1)72% der Gesamt-Niederschläge auf der Erde fallen zwischen den Breitengraden 40° N und 40° S. Unter der Voraussetzung, daß während der letzten Eiszeit die Verdunstung — und damit die Niederschläge — 20% niedriger waren als ... -
A novel experimental approach for nanostructure analysis: simultaneous small-angle X-ray and neutron scattering
(Journal of Applied Crystallography, 2020)Exploiting small-angle X-ray and neutron scattering (SAXS/SANS) on the same sample volume at the same time provides complementary nanoscale structural information in two different contrast situations. Unlike an independent ... -
A novel method for the quantitative morphometric characterization of soluble salts on volcanic ash
; ; ; ; (Bulletin of Volcanology, 2021-12-06)
Formation of soluble sulfate and halide salts on volcanic ash particles via syn-eruptive interactions between ash surfaces and magmatic gases is a ubiquitous phenomenon in explosive eruptions. Surficial salts may be rapidly ... -
A Numerical Model of Tracer Transport in a Non-isothermal Two-Phase Flow System for CO2 Geological Storage Characterization

A Parameterization of Cirrus Cloud Formation: Revisiting Competing Ice Nucleation
(Journal of Geophysical Research: Atmospheres, 2022-09-24)
This study develops an advanced physically‐based parameterization of heterogeneous ice nucleation in cirrus clouds that includes an updated parameterization of stochastic homogeneous freezing of supercooled solution droplets. ... -
A partial skeleton of Septencoracias from the early Eocene London Clay reveals derived features of bee-eaters (Meropidae) in a putative stem group roller (Aves, Coracii)
(Palaeobiodiversity and Palaeoenvironments, 2021-09-13)
A partial skeleton of the putative stem group roller Septencoracias is described from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK). With an age of about 55 million years, the bones represent one of the ... -
A partition-enhanced least-squares collocation approach (PE-LSC)
; ; ; (Journal of Geodesy, 2021-07-31)
We present a partition-enhanced least-squares collocation (PE-LSC) which comprises several modifications to the classical LSC method. It is our goal to circumvent various problems of the practical application of LSC. While ... -
A permafrost glacial hypothesis – Permafrost carbon might help explaining the Pleistocene ice ages
(E&G – Quaternary Science Journal; Vol.61, No. 1)
Während der letzten ~100 ka Glazial-Interglazial-Zyklen war die Konzentration des Treibhausgases CO2 in der Atmosphäre eng mit der globalen Temperatur gekoppelt. Die Gründe fuür die CO2 Konzentrationsschwankungen wurden ... -
A post-IR IRSL chronology and dust mass accumulation rates of the Nosak loess-palaeosol sequence in northeastern Serbia
; ; ; ; ; ; (Boreas, 2020)
In the Middle Danube Basin, Quaternary deposits are widely distributed in the Vojvodina region where they cover about 95% of the area. Major research during the last two decades has been focused on loess deposits in the ... -
A probabilistic approach to estimating residential losses from different flood types
; ; ; ; ; ; ; ; (Natural Hazards, 2020-12-02)
Residential assets, comprising buildings and household contents, are a major source of direct flood losses. Existing damage models are mostly deterministic and limited to particular countries or flood types. Here, we compile ...
