Algorithmic Differentiation for Sensitivity Analysis in Cloud Microphysics
; ; ; (Journal of Advances in Modeling Earth Systems, 2022-07-12)
The role of clouds for radiative transfer, precipitation formation, and their interaction with atmospheric dynamics depends strongly on cloud microphysics. The parameterization of cloud microphysical processes in weather ... -
Alkalibasaltische Intrusionen im Devon der Lahnmulde (südliches Rheinisches Schiefergebirge)
(Mainzer geowissenschaftliche Mitteilungen; 17. 1988)Schichtkonkordante Intrusionen basischer Schmelzen sind im Paläozoikum der südwestlichen Lahnmulde verhältnismäßig rar. Im Gegensatz zu den zahlreichen metatholeiitischen Lagergängen der mittleren und östlichen Lahnmulde, ... -
Alles Matsch? – Bildungs- und Öffentlichkeitsarbeit in Mooren
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 52; 2022)Moore sind in aller Munde. Stehen wir doch alle vor den globalen Herausforderungen wie Klimawandel und Biodiversitätsverlust. Die im vergangenen Jahr noch schnell beschlossene Moorschutzstrategie der Bundesregierung wurde ... -

Mit der Energiedichte Ψ im darcyschen Gesetz sind ... -
Alpine architecture and kinematics of deformation of the northern Pelagonian nappe pile in the Hellenides
(Austrian Journal of Earth Sciences, 2010)Geological mapping and detailed structural investigations combined with geochronological and stratigraphic data, as well as fissiontrack age dating carried out on the northern part of the Pelagonian basement and the ... -
Alte Strandlinien des Pleistozäns in Nordamerika und Europa
(E&G – Quaternary Science Journal; Vol.11, No. 1)An der Atlantischen Ostküste der Vereinigten Staaten sind — abgesehen von dem Silver-Bluff-Strand, der in das klimatische Optimum der Postglazialzeit gestellt wird — drei höhere alte Strände vorhanden: der Pamlico-Strand ... -
Alternating Emission Features in Io's Footprint Tail: Magnetohydrodynamical Simulations of Possible Causes
; (Journal of Geophysical Research: Space Physics, 2022-04-28)
Io's movement relative to the plasma in Jupiter's magnetosphere creates Alfvén waves propagating along the magnetic field lines which are partially reflected along their path. These waves are the root cause for auroral ... -
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 ... -
Aluminum Components in Bridgmanite Coexisting With Corundum and the CF‐Phase With Temperature
; ; ; ; (Journal of Geophysical Research: Solid Earth, 2023-01-22)
Abstract Phase relations in the MgSiO3–MgAl2O4–Al2O3 system are investigated at 27 GPa and 2000–2600 K using a multi‐anvil apparatus. The AlAlO3 content ... -
Always ready? Primary production of Arctic phytoplankton at the end of the polar night
(Limnology and Oceanography Letters, 2021-11-11)
The end of the polar night with the concurrent onset of photosynthetic biomass production ultimately leads to the spring bloom, which represents the most important event of primary production for the Arctic marine ecosystem. ... -
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 ... -
Amplification of the Atlantic Multidecadal Oscillation associated with the onset of the industrial-era warming
(Scientific Reports, 2017) -
Amplified Arctic Surface Warming and Sea Ice Loss Due to Phytoplankton and Colored Dissolved Material
; Losa, Svetlana N.; ; ; (Geophysical Research Letters, 2020-11-02)
Optically active water constituents attenuate solar radiation and hence affect the vertical distribution of energy in the upper ocean. To understand their implications, we operate an ocean biogeochemical model coupled to ... -
An Adaptive Hybrid Vertical Equilibrium/Full‐Dimensional Model for Compositional Multiphase Flow
; ; ; ; (Water Resources Research, 2022-01-21)
Efficient compositional models are required to simulate underground gas storage in porous formations where, for example, gas quality (such as purity) and loss of gas due to dissolution are of interest. We first extend the ... -
An adaptive shallow water model on the sphere
(Univ. Bremen, 2009)
This thesis describes the adaptive shallow water model PLASMA-FEMmE. It solves on the sphere the shallow water equations, the prototype for partial differential equations in atmospheric modeling, using a semi-implicit ... -
An analysis of the evolution of reactive species in Fe0/H2O systems.
(Journal of hazardous materials, 2009-09-15)
Aqueous contaminant removal in the presence of metallic iron (e.g. in Fe(0)/H(2)O systems) is characterized by the large diversity of removing agents. This paper analyses the synergistic effect of adsorption, co-precipitation ... -
An Analytical Framework for Determining the Ecological Risks of Wastewater Discharges in River Networks Under Climate Change
; ; ; ; (Earth's Future, 2022-10-03)
Over the last decades, treatment of domestic wastewater promoted by environmental regulations have reduced human health risks and improved water quality. However, ecological risks caused by effluents of wastewater treatment ... -
An ancient process in a modern mollusc: early development of the shell in Lymnaea stagnalis
(BMC Developmental Biology, 2013)Background The morphological variety displayed by the molluscan shell underlies much of the evolutionary success of this phylum. However, the broad diversity of shell forms, sizes, ornamentations and functions contrasts ... -
An andesitic sill complex in the Southern Permian Basin: volcanogenetic model and stratigraphic implications
; ; ; ; ; ; ; ; (International Journal of Earth Sciences, 2020-07-28)
Subvolcanic intrusions are highly variable in shape and structure, and occur in nearly all parts of the upper crust, as a result of extensive volcanic activity. Processes of subvolcanics interacting with the host rock are ... -
An Antarctic molluscan biomineralisation tool-kit
(Scientific Reports, 2016)The Antarctic clam Laternula elliptica lives almost permanently below 0 °C and therefore is a valuable and tractable model to study the mechanisms of biomineralisation in cold water. The present study employed a ...
