Observing Earth’s magnetic environment with the GRACE-FO mission
(Earth, Planets and Space, 2021-02-15)The Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission carries magnetometers that are dedicated to enhance the satellite’s navigation. After appropriate calibration and characterisation of artificial ... -
Observing noctilucent clouds
(Internat. Assoc. of Geomagnetism & Aeronomy, 2006)This manual and instruction book was written by a group of active researchers, both professional and amateur. There are chapters giving practical advice for taking visual observations, photographing the clouds with film ... -
Ocean Bottom Pressure Variability: Can It Be Reliably Modeled?
(Journal of Geophysical Research: Oceans, 2020)Ocean bottom pressure (OBP) variability serves as a proxy of ocean mass variability, the knowledge of which is needed in geophysical applications. The question of how well it can be modeled by the present general ocean ... -
Ocean Model Formulation Influences Transient Climate Response
(Journal of Geophysical Research: Oceans, 2021-12-05)The transient climate response (TCR) is 20% higher in the Alfred Wegener Institute Climate Model (AWI‐CM) compared to the Max Planck Institute Earth System Model (MPI‐ESM) whereas the equilibrium climate sensitivity (ECS) ... -
On classification of logging data
(Univ. Clausthal, 2006)Die Erkennung stratigraphischer Einheiten innerhalb von marinen Sedimentablagerungen wird üblicherweise durch eine kombinierte Interpretation von Seismik-, Bohrlochsonden- und Kern-Daten vorgenommen. Im Falle von mehrdeutigen ... -
On gravity wave parameterisation in vicinity of low‐level blocking
(Atmospheric Science Letters, 2022-03-07)This note is framed as an open question to the community regarding parameterisation schemes using the blocking layer depth to reduce the orographic gravity wave drag. It is the purpose of this note to argue that the current ... -
On intrinsic uncertainties in earth system modelling
(Univ. Potsdam, 2006)Various types of uncertainty plague climate change simulation, which is, in turn, a crucialelement of Earth System modelling. This fact was recognized for example in the Third Assessment Report (TAR) of the Intergovernmental ... -
On the determination of the atmospheric outer scale length of turbulence using GPS phase difference observations: the Seewinkel network
(Earth, Planets and Space, 2020-12-04)Microwave electromagnetic signals from the Global Navigation Satellite System (GNSS) are affected by their travel through the atmosphere: the troposphere, a non-dispersive medium, has an especial impact on the measurements. ... -
On the Dynamical Importance of Gravity Wave Sources Distributed Over Different Heights in the Atmosphere
(Journal of Geophysical Research: Space Physics, 2023-03-15)Gravity waves (GWs) are generated at all altitudes in the atmosphere, but sources above the lower stratosphere are rarely considered by parameterizations employed in general circulation models. This study assesses the ... -
On the evaluation of climate change impact models
(Wiley Interdisciplinary Reviews: Climate Change, 2022-03-03)In‐depth understanding of the potential implications of climate change is required to guide decision‐ and policy‐makers when developing adaptation strategies and designing infrastructure suitable for future conditions. ... -
On the exploration of a marine aquifer offshore Israel by long-offset transient electromagnetics
(Geophysical Prospecting, 2019)The existence of aquifers extending from land beneath the sea floor up to a distance of several kilometres has been observed and examined all over the world. The coastal aquifer of Israel is a heavily used groundwater ... -
On the influence of local inhomogeneities on cosmological observables - from galaxies to the microwave background
(Univ. Bielefeld, 2007)Despite the good consistency of the cosmological standard model with the bulk of present observations, a number of unanticipated features have recently been detected within large-angle data of the Cosmic Microwave Background. ... -
On the Limitations and Implications of Modeling Heat Transport in Porous Aquifers by Assuming Local Thermal Equilibrium
(Water Resources Research, 2020)Heat transport in natural porous media, such as aquifers or streambeds, is generally modeled assuming local thermal equilibrium (LTE) between the fluid and solid phases. Yet, the mathematical and hydrogeological conditions ... -
On the possibility of getting traceable time and frequency measurements via GNSS receivers
(GPS Solutions, 2020-09-02)The realization of Coordinated Universal Time, one of the tasks of the International Bureau of Weights and Measures, relies on a network of international time links which currently is organized in a star-like scheme that ... -
On the relevance of adhesion - applications to Saturn's rings
(Univ. Potsdam, 2006)Seit ihrer Entdeckung im Jahre 1610 durch Galileo Galilei faszinieren die Ringe des Saturn sowohl Laien als auch Experten. Planetare Ringe finden sich in der Äquatorialebene aller vier Riesenplaneten unseres Sonnensystems ... -
On the representation of atmospheric circulation modes in regional climate models over Western Europe
(International Journal of Climatology, 2022-07-27)Atmospheric circulation is a key driver of climate variability, and the representation of atmospheric circulation modes in regional climate models (RCMs) can enhance the credibility of regional climate projections. This ... -
On the Resolution of Triangular Meshes
(Journal of Advances in Modeling Earth Systems, 2022-10-08)It is generally agreed that the resolution of a regular quadrilateral mesh is the side length of quadrilateral cells. There is less agreement on the resolution of triangular meshes, exacerbated by the fact that the numbers ... -
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) ... -
