Ionospheric Observatory Development At Mario Zucchelli Station

, 2004
Since 1995 Italian Ionospheric Antarctic Observatory at Terra Nova Bay, now “MARIO ZUCCHELLI”, station (geographic coordinates: 74.70°S, 164.11°E) performs continuous and systematic ionospheric vertical soundings.

Present‐Day Kinematics of Continental Greece and Balkans Revealed by Sentinel‐1 InSAR Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Balkan Peninsula hosts the highest seismic activity in Europe, marked by numerous Mw6+ earthquakes in diverse tectonic settings. Assessing tectonic surface deformation is crucial to understand the forces controlling kinematics and, ultimately, constraining geodynamic models. However, because measuring slow velocity rates (a few mm/yr) with

Variation of Venusian Gravity Wave Absolute Momentum Fluxes and Drag as Retrieved From the Akatsuki Mission

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Using temperature retrievals from Akatsuki radio occultation measurements, we characterize gravity wave activity as a function of vertical wavenumber and altitude. For the first time, we estimate the absolute horizontal momentum fluxes and the magnitude of the gravity wave drag (i.e., wave acceleration), assuming a horizontal wavelength of 300

ASSESSMENT OF THE SEVERE GEOMAGNETIC STORM ON MAY 10-11, 2024 EFFECTS ON THE GEOMAGNETIC FIELD AND IONOSPHERE OVER THE INDONESIAN REGION

Rudarsko-geološko-naftni Zbornik
The severe geomagnetic storm on May 11, 2024, is the largest space weather phenomenon in the 25th solar cycle. This paper presents the impact of that severe geomagnetic storm (Dst = -412 nT) on the geomagnetic field and ionosphere over Indonesia ...

Michigan Geospace Model With Ensemble Forecasting and Particle Filtering: Modeling the May 2024 Extreme Storm

Space Weather, Volume 24, Issue 9, September 2026.
Abstract This paper introduces an updated version of the University of Michigan Geospace model. The Geospace model has been used for operational forecasting at the Space Weather Modeling Center of the National Oceanic and Atmospheric Agency since 2016 with regular updates. The current operational version, Geospace V2, was launched in 2021 and is driven

Robust Machine Learning–Based Ionospheric Delay Grid Modeling for PPP‐RTK Under Sparse Reference Stations and Severe Geomagnetic Disturbance

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Sparse reference station networks and severe geomagnetic disturbances can significantly degrade the accuracy of regional ionospheric delay modeling at the network side, thereby reducing the positioning performance of PPP‐RTK. To address this issue, this study proposes a machine learning‐based ionospheric delay grid modeling method that finely ...
