Cable reverberations during wireline distributed acoustic sensing measurements: their nature and methods for elimination
(Geophysical Prospecting, 2021-05-16)The application of distributed acoustic sensing in borehole measurements allows for the use of fibre optic cables to measure strain. This is more efficient in terms of time and costs compared with the deploying of conventional ... -
Calibrating receiver-type-dependent wide-lane uncalibrated phase delay biases for PPP integer ambiguity resolution
(Journal of Geodesy, 2021-06-29)Wide-lane (WL) uncalibrated phase delay (UPD) is usually derived from Melbourne–Wübbena (MW) linear combination and is a prerequisite in Global Navigation Satellite Systems (GNSS) precise point positioning (PPP) ambiguity ... -
Calibration of the Heat Flow and Physical Properties Package (HP 3) for the InSight Mars Mission
(Earth and Space Science, 2019)The (HP 3) of the InSight Mars mission is an instrument package to measure the Martian geothermal heat flow. The instrument's platinum resistance temperature sensors have been calibrated between −75 and +55 °C, and ... -
Californian Wildfire Smoke Over Europe: A First Example of the Aerosol Observing Capabilities of Aeolus Compared to Ground‐Based Lidar
(Geophysical Research Letters, 2021-04-28)In September 2020, extremely strong wildfires in the western United States of America (i.e., mainly in California) produced large amounts of smoke, which was lifted into the free troposphere. These biomass‐burning‐aerosol ... -
Can global rainfall estimates (satellite and reanalysis) aid landslide hindcasting?
(Landslides, 2021-06-19)Predicting rainfall-induced landslides hinges on the quality of the rainfall product. Satellite rainfall estimates or rainfall reanalyses aid in studying landslide occurrences especially in ungauged areas, or in the absence ... -
Catastrophic cooling in solar coronal loops - thermal instability as a road to complex evolution
(Univ. Freiburg (Breisgau), 2005)Satellite observations with high spatial and temporal resolution have revealed the highly dynamic nature of the solar corona and enabled us to study physical processes in the outer atmosphere of our mother star in great ... -
Changes in the Tropical Lapse Rate due to Entrainment and Their Impact on Climate Sensitivity
(Geophysical Research Letters, 2021-09-16)The tropical temperature in the free troposphere deviates from a theoretical moist‐adiabat. The overall deviations are attributed to the entrainment of dry surrounding air. The deviations gradually approach zero in the ... -
Channelised and open-slope processes of mass sediment transport - their morphological and seismic characterisation from selected Atlantic high productivity regions
(Univ. Bremen, 2005)Sediment transport, high productivity, submarine canyon, submarine slide, excess pore-pressure, weak layers, slope failure. - The study investigates processes of mass sediment transport in two geologically unique Atlantic ... -
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 ... -
Characterization and Evolution of Organized Shallow Convection in the Downstream North Atlantic Trades
(Journal of Geophysical Research: Atmospheres, 2021-08-26)Four previously identified patterns of meso‐scale cloud organization in the trades — called Sugar, Gravel, Flowers, and Fish — are studied using long‐term records of ground‐based measurements, satellite observations and ... -
Characterization of differential throughfall drop size distributions beneath European beech and Norway spruce
(Hydrological Processes, 2019)Forest canopies present irregular surfaces that alter both the quantity and spatiotemporal variability of precipitation inputs. The drop size distribution (DSD) of rainfall varies with rainfall event characteristics and ... -
Characterization of silty to fine-sandy sediments with SH waves: full waveform inversion in comparison with other geophysical methods
(Near Surface Geophysics, 2020)We apply seismic full waveform inversion to SH- and Love-wave data for investigating the near-surface lithology at an archaeological site. We evaluate the resolution of the applied full waveform inversion algorithm through ... -
Characterization of the stellar variability in CoRoT fields with BEST telescopes
(Univ. Berlin, 2009)The first extrasolar planet 51 Peg b around the G-type star has been reported in 1995. The planet with few Jupiter masses orbiting its star very closely was detected by measurement of the oscillation in the radial velocity ... -
Charakterisierung hydrologischer Material-Eigenschaften mittels Multi Step Outflow (MSO) Experimenten
(2012-03-05)Die Kenntnis hydrologischer Eigenschaften ist essentiell für das Grundwassermanagement. Im Rahmen eines Projektes zur Verknüpfung mit elektrischen Eigenschaften, welche nicht-invasiv bestimmbar sind (Spektrale Induzierte ... -
Chemisch-physikalische Zusammensetzung der Ganymedoberfläche - Zusammenhänge mit geologischen Strukturen und deren Gestaltungsprozessen
(Univ. Berlin, 2006)Die Untersuchung der Oberflächenzusammensetzung von Ganymed basiert auf Daten des abbildenden Spektrometers NIMS an Bord der Raumsonde Galileo, das die Ganymedoberfläche im Spektralbereich des Nahen Infrarot detektiert. ... -
Chiral symmetry restoration and deconfinement in neutron stars
(Univ. Frankfurt (Main), 2009)Neutron stars are very dense objects. One teaspoon of their material would have a mass of five billion tons. Their gravitational force is so strong that if an object were to fall from just one meter high it would hit the ... -
Chromospheric and coronal activity - analysing optical spectra of M dwarfs
(Univ. Hamburg, 2005)Unter stellarer Aktivität werden eine Reihe von Phänomenen in den unterschiedlichen Atmosphärenschichten zusammengefasst, die eng mit dem Magnetfeld des einzelnen Sterns verbunden sind. Da eine direkte Auflösung der ... -
Chromospheric and coronal activity in solar-like stars
(Univ. Hamburg, 2008)The term "stellar activity" summarizes a number of phenomena on the stellar surface and in the stellar atmosphere. The origin of many of these phenomena are changes in the structure of the stellar magnetic field. While ... -
Circulation pattern controls of wet days and dry days in Free State, South Africa
