Analysis of Errors in Gravity Derived from the FALCON Airborne Gravity Gradiometer

, 2008
FALCON airborne gravity gradient data can be converted to vertical gravity via direct integration techniques (Gunn, 1975) or equivalent source methods (Dampney, 1969), and hence compared with conventional gravimetry data.

Evaluation of Novel Airborne Gravity Levelling Methods [PDF]

In dynamic gravimetry, i.e. airborne and shipborne gravimetry, levelling methods are used to refine gravity disturbance results based on neighbouring trajectories.

WACCM‐RR: A Regionally‐Refined Version of the Whole Atmosphere Community Climate Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract We introduce the Whole Atmosphere Community Climate Model with Regional Refinement (WACCM‐RR) and study the impact of directly resolving gravity waves (GWs) in the mesosphere and lower thermosphere (MLT; 70–140 km). Two simulations of 2010 are compared: “Non‐RR” is a standard WACCM case with a horizontal resolution of ∼1° (111 km) globally ...

Eruption Source Parameters in Volcanic Plume Modeling: Advances, Challenges, and Future Directions

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Accurately predicting the atmospheric dispersion of volcanic ash and gases is crucial for both scientific understanding and hazard mitigation. Estimating Eruption Source Parameters (ESP), such as mass eruption rate, plume height, duration, and particle size distribution and properties, remains challenging due to the complex nature of volcanic ...

The determination of the geoid from airborne gravity data.

, 2001
Based on basic principles of potential theory, a proper definition of geodetic boundary-value problems, which are involved in the mathematical model for the determination of the band-limited gravimetric geoid grom airborne gravity, is presented including

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Airborne Strapdown Gravity Measurements for Geodesy and Geophysics [PDF]

, 2018
The determination of gravity from an airborne platform, commonly known as airborne gravimetry, has been recognised as an operational procedure since the 1990s, using springtype gravimeters mounted on a stabilised platform.

Rock Physics of the Critical Zone: Models, Inversion, and Interpretation

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Rock physics models link geophysical measurements with subsurface petrophysical properties, such as porosity, mineral composition, and fluid saturation. While originally developed for hydrocarbon exploration, these models are increasingly applied in the near surface for quantitative interpretation of geophysical data.

Effect of Sintering Aid Composition and Porosity on the Oxyacetylene Torch Response of Silicon Nitride for RF Windows

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
Silicon nitride samples were slip cast using yttrium oxide–aluminum oxide and ytterbium oxide sintering aids to fabricate plates with up to 40% porosity and compare them to a fully dense commercial standard. Silicon nitride plates were tested with an oxyacetylene torch to investigate changes in front and back face temperature, spectral emissivity ...
