Identification of the Semangko Fault in Sumatra, Indonesia, based on gradient gravity data analysis [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2022
The Semangko Fault (SF) is a major active fault that extends across from Aceh (in northern part) to Lampung Province (in southern part) of Sumatra Island, contributing to much deformation and high seismicity along the fault. The fault affects a pattern

Refined discrete and empirical horizontal gradients in VLBI analysis [PDF]

open access: yesJournal of Geodesy, 2018
Missing or incorrect consideration of azimuthal asymmetry of troposphere delays is a considerable error source in space geodetic techniques such as Global Navigation Satellite Systems (GNSS) or Very Long Baseline Interferometry (VLBI). So-called horizontal troposphere gradients are generally utilized for modeling such azimuthal variations and are ...

Ray Tracing with Horizontal and Vertical Gradients [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1970
Ray paths are found in a medium with a sound speed varying in two dimensions. The velocity field is approximated in a triangular region by a linear function of range and depth. The assumed velocity is continuous, but the gradient of the velocity is discontinuous across the boundaries of the triangular region.

Nonlinear 3-D inversion of gravity data over a sulfide ore body [PDF]

open access: yesGeofísica Internacional, 2000
The horizontal gravity gradient and the principle of superposition of potential fields are used in the interpretation of gravity data from a sulfide ore body in terms of a 3-D structure of densities.

On wake modeling, wind-farm gradients, and AEP predictions at the Anholt wind farm [PDF]

open access: yesWind Energy Science, 2018
We investigate wake effects at the Anholt offshore wind farm in Denmark, which is a farm experiencing strong horizontal wind-speed gradients because of its size and proximity to land.

Statistical Analysis of Atmospheric Delay Gradient and Rainfall Prediction in a Tropical Region

open access: yesRemote Sensing
In recent years, precipitable water vapor has emerged as a key atmospheric parameter in weather prediction research. However, relying on only one parameter does not always accurately predict rainfall, as other atmospheric parameters also contribute to ...

Exceptionally strong summer-like zonal wind reversal in the upper mesosphere during winter 2015/16 [PDF]

open access: yesAnnales Geophysicae, 2017
The 2015/16 Northern Hemisphere winter season was marked by peculiarities in the circulation pattern in the high-latitude mesopause region. Wind measurements from the Andenes (69° N, 13° E) meteor radar show westward winds below 84 km and eastward ...
