Deformation induced topographic effects in inversion of temporal gravity changes: First look at Free Air and Bouguer terms

open access: yesContributions to Geophysics and Geodesy, 2015
We review here the gravitational effects on the temporal (time-lapse) gravity changes induced by the surface deformation (vertical displacements). We focus on two terms, one induced by the displacement of the benchmark (gravity station) in the ambient ...

Curl free pressure gradients over orography in a solution of the fully compressible Euler equations with implicit treatment of acoustic and gravity waves [PDF]

open access: yes, 2014
Steep orography can cause noisy solutions and instability in models of the atmosphere. A new technique for modelling flow over orography is introduced which guarantees curl free gradients on arbitrary grids, implying that the pressure gradient term is ...

Reservoir Identification of Bac-Man Geothermal Field Based on Gravity Anomaly Analysis and Modeling

open access: yesJournal of Applied Science and Engineering, 2021
The Bac-Man gravity modeling was carried out to describe the geological structures that control the geothermal system and estimate the area of the geothermal reservoir. A total of 125 data points were used to produce a complete Bouguer anomaly map of the

Calibrating error variance and scaling global covariance function of geoid gradients for optimal determinations of gravity anomaly and gravity gradient from altimetry

open access: yesJournal of Geodesy, 2022
With the advancements of satellite altimeter technology and data volume, the accuracy and spatial resolution of altimeter-derived marine gravity fields have been steadily improved. Ideally, a best marine gravity field from multi-altimeter missions is one

Surfactant-induced gradients in the three-dimensional Belousov-Zhabotinsky reaction [PDF]

open access: yes, 2011
Scroll waves are prominent patterns formed in three-dimensional excitable media, and they are frequently considered highly relevant for some types of cardiac arrhythmias.

Double-component convection due to different boundary conditions in an infinite slot diversely oriented to the gravity [PDF]

open access: yes, 2007
Onset of small-amplitude oscillatory and both small- and finite-amplitude steady double-component convection arising due to component different boundary conditions in an infinite slot is studied for various slot orientations to the gravity.

Chemical Cartography with APOGEE: Large-scale Mean Metallicity Maps of the Milky Way [PDF]

open access: yes, 2013
We present Galactic mean metallicity maps derived from the first year of the SDSS-III APOGEE experiment. Mean abundances in different zones of Galactocentric radius (0 < R < 15 kpc) at a range of heights above the plane (0 < |z| < 3 kpc), are derived ...
