A Shape Optimization Approach for Inferring Sources of Volcano Ground Deformation
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract One of the main goals of volcano geodesy is to improve the understanding of how an increase in pressure related to magma accumulation causes ground deformation in order to evaluate volcanic unrest. The inversion methods used for this purpose rely on a parametrization of the shape of the crustal volume in which pressure changes due to magma ...

Sudden Ionospheric Disturbances Generated by Solar Flares—Not so Sudden?
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract It is known that solar flares generate instantaneous ionization enhancement, referred to as sudden ionospheric disturbance (SID), that occurs simultaneously across the entire dayside. In this work, we use high‐rate 1‐s data of total electron content (TEC) to analyse ionospheric response to 13 solar flares that occurred in 2003–2023.

Tropospheric delays in ground-based GNSS Multipath Reflectometry – experimental evidence from coastal sites [PDF]
, 2017 Recent studies have demonstrated the utility of ground based GNSS Multipath Reflectometry (GNSS-MR) for sea level studies. Typical root-mean-square (RMS) differences of GNSS-MR derived sea level time series with respect to nearby tide gauges are on the ...

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract The threefold daytime electron density increases, along with strong poleward meridional winds exceeding 200 m/s were captured by Sanya Incoherent Scatter Radar (SYISR) during the geomagnetic storm of 12 November 2025. The great ionospheric enhancements were extending to mid‐latitudes over 40° observed by total electron content (TEC) from ...
