Mineralogical analysis and iron abundance estimation of the Moon using the SIR-2, HySI and M3 spectrometers on-board the munar orbiter chandrayaan-1
(Techn. Univ. Zugl.: Clausthal, 2012)
The work presented in this thesis is focused on mineralogical studies of the Moon aiming to create maps of iron abundances. We used the data from visible to near-infrared (VISNIR) spectrometers on-board Chandrayaan-1 ... -
Minimal Recipes for Global Cloudiness
; ; ; ; ; ; (Geophysical Research Letters, 2022-10-26)
Clouds are primary modulators of Earth's energy balance. It is thus important to understand the links connecting variabilities in cloudiness to variabilities in other state variables of the climate system, and also describe ... -
Minimisation of optical pathlength noise for the detection of gravitational waves with the spaceborne laser interferometer LISA and LISA pathfinder
(Univ. Hannover, 2007)Gravitational waves were predicted by Albert Einstein in 1916 as a consequence of his theory of general relativity. Hulse and Taylor provided indirect experimental evidence of their existence based on the increasing rotation ... -
Missing Rainfall Extremes in Commercial Microwave Link Data Due To Complete Loss of Signal
; ; (Earth and Space Science, 2023-02-06)
An important aspect of rainfall estimation is to accurately capture extreme events. Commercial microwave links (CMLs) can complement weather radar and rain gauge data by estimating path‐averaged rainfall intensities near ... -
Mit Geophysik in die Zukunft - eine Denkschrift 1997
(Mitteilungen - Deutsche Geophysikalische Gesellschaft ; 1996,4)Wird heute genug für die wissenschaftliche und technologische Steuerung des sich immer rasanter vollziehenden globalen und regionalen Wandels der Bio- und Geosphäre getan? Hat die internationale Gemeinschaft die Kraft zu ... -

Model building and imaging with reflection data
(Univ. Hamburg, 2002)The purpose of the first part of this dissertation was to develop a migration algorithm for converted waves, and a tomographic method for estimating an interval shear wave velocity model. The developed algorithm is based ... -
Modeling and inversion in weakly anisotropic media
(Univ. Hamburg, 2004)Mit der Annahme schwacher Anisotropie vereinfachen sich die Lösungen der Modellierung und Inversion anisotroper Medien. Üblicherweise werden Perturbation-Methoden zur Beschreibung der Wellen-Ausbreitung in schwach anisotropen ... -
Modeling atmospheres of classical novae in X-rays with PHOENIX
(Univ. Hamburg, 2005)PHOENIX has been used to calculate model atmospheres of classical novae in the X-ray spectral range. The models account for an expanding, one-dimensional spherically symmetric medium in full non-local thermodynamic ... -
Modeling cloud properties over the 79 N Glacier (Nioghalvfjerdsfjorden, NE Greenland) for an intense summer melt period in 2019
; ; (Quarterly Journal of the Royal Meteorological Society, 2022-11-04)
Long believed to be insignificant, melt activity on the Northeast Greenland Ice Stream (NEGIS) has increased in recent years. Summertime Arctic clouds have the potential to strongly affect surface melt processes by regulating ... -
Modeling Fluid Reinjection Into an Enhanced Geothermal System
; (Geophysical Research Letters, 2020)
Abstract The manuscript analyzes the stimulation for an Enhanced Geothermal System development in Acoculco, Mexico. Using an analytical penny-shaped hydraulic fracture model covering different propagation regimes, we ... -
Modeling light curves of type Ia supernovae
(Univ. Hamburg, 2009)The main topic of this work is the introduction of time dependence into PHOENIX. This has been achieved for both the radiation field and the matter in the SN Ia model atmosphere. First, time dependence in the radiative ... -
Modeling ocean-induced rapid Earth rotation variations: an update
; ; ; (Journal of Geodesy, 2021-09-07)
We revisit the problem of modeling the ocean’s contribution to rapid, non-tidal Earth rotation variations at periods of 2–120 days. Estimates of oceanic angular momentum (OAM, 2007–2011) are drawn from a suite of established ... -
Modeling of Planetary Wave Influences on the Pre‐reversal Enhancement of the Equatorial F Region Vertical Plasma Drift
