The alpine Swiss-French airborne gravity survey
, 2017 In February 1998, a regional-scale, airborne gravity survey was carried out over the French Occidental Alps within the framework of the GéoFrance 3-D research program.The survey consisted of 18 NS and 16 EW oriented lines with a spacing of 10 and 20 km ...

Airborne gravity tests in the Italian area to improve the geoid model of Italy
, 2009 Airborne gravimetry is an important method for measuring gravity over large unsurveyed areas. This technology has been widely applied in Canada, Antarctica and Greenland to map the gravity fields of these regions and in recent years, in the oil industry.

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Drained and cultivated grasslands on peat soils behave as a significant source of greenhouse gasses by oxidation. However, the lack of empirical estimates of carbon losses from peatlands with adequate spatial and temporal resolution has forced researchers to rely on process‐based model approximations to make quantitative, regional‐ or national‐

Innovative airborne geophysical strategies to assist the exploration of critical metal systems
Geosystems and GeoenvironmentCritical metals are essential in sustaining the high technology and the green energy transition of modern societies. The future discovery of new critical metal deposits will likely be made at increasing depths and under thick cover sequences.

Long‐Lived Sub‐Micron Desert Dusts are Important Ice‐Nucleating Particles in the Polar Regions
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Ice‐nucleating particles (INPs) modify the distribution and radiative properties of mixed‐phase clouds, making them a key component of the climate system. However, we have a very limited understanding of INPs, particularly in polar regions that are remote from major low‐latitude sources.

Tropical Cyclones Drive Enhanced Inorganic Iodine in the Mid‐Latitude Upper Troposphere
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Halogens deplete tropospheric and stratospheric ozone, but the role of iodine is still elusive. Atmospheric iodine mainly originates from marine inorganic (I2, HOI) and organic (CH3I, CH2I2, CH2IBr, and CH2ICl) emissions. We report on airborne measurements of atmospheric iodine oxide (IO) concentrations up to 15 km altitude from two flights of

Wilson's Atmospheric Electron Accelerator: A Centennial Perspective
Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract As of the time of writing this letter, we mark the centennial of Wilson's runaway electrons proposed in 1925. Owing to instrumentation limitations, Wilson and his students could not detect the particles anticipated by theory Chilingarian et al. (2025, https://doi.org/10.1029/2024jd042350).
