On the Feasibility of Seafloor Topography Estimation from Airborne Gravity Gradients: Performance Analysis Using Real Data

open access: yesRemote Sensing, 2020
Compared with airborne gravimetry, a technique frequently used to infer the seafloor topography at places inaccessible to ship soundings due to the presence of ice shelf or ice mélange, airborne gravity gradiometry inherently could achieve higher spatial

High-Resolution Cooperate Density-Integrated Inversion Method of Airborne Gravity and Its Gradient Data

open access: yesRemote Sensing, 2021
Airborne (or satellite) gravity measurement is a commonly used remote sensing method to obtain the underground density distribution. Airborne gravity gradiometry data have a higher horizontal resolution to shallower causative sources than airborne ...

Airborne measurements of gravity wave breaking at the tropopause [PDF]

open access: yesGeophysical Research Letters, 2003
A breaking atmospheric gravity wave was investigated with a combination of airborne in‐situ dynamical measurements and ground‐based VHF radar observations. The wave was generated by flow over mountains and it was observed to break near the tropopause. The measurements reveal that the wave was overturning at the tropopause and that the initial breakdown

Analysis of Alabama Airborne Gravity at Three Altitudes: Expected Accuracy and Spatial Resolution from a Future Tibetan Airborne Gravity Survey

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2013
In situ airborne gravity data at altitudes of 11, 6.3, and 1.7 km over a smooth area of Alabama are used to assess gravity accuracy and errors in upward and downward continuations. Analysis of the Alabama free-air anomaly gravity data at crossover points

Geoid determination using airborne gravity vectors

open access: yesEarth, Planets and Space
In traditional airborne gravimetry, the vertical component of the gravity vector is used as an approximation of the measured magnitude of the gravity vector, which enters the determination of the local geoid.

Polar gravity fields from GOCE and airborne gravity [PDF]

open access: yes, 2011
Airborne gravity, together with high-quality surface data and ocean satellite altimetric gravity, may supplement GOCE to make consistent, accurate high resolution global gravity field models. In the polar regions, the special challenge of the GOCE polar gap make the error characteristics of combination models especially sensitive to the correct merging
