Space Weather, Volume 24, Issue 3, March 2026.Abstract Complex space weather, such as typhoons and solar activity, can cause heavy rainfall and ionospheric disturbances, affecting the quality of Global Navigation Satellite System (GNSS) signals. Among GNSS positioning techniques, Precise Point Positioning Real‐time Kinematic (PPP‐RTK) uses atmospheric corrections and bias products to achieve fast ...

Geomagnetic extreme statistics for Europe [PDF]
, 2009 Rapidly changing geomagnetic field variations constitute a natural hazard, for example to grounded power grids and pipeline networks. To understand this hazard we have continuous magnetic measurements across the world for typically less than 100 years.

Solar sources of geomagnetic storms
Eos, Transactions American Geophysical Union, 1992 Because geomagnetic storms can have important effects on communications and electrical power distribution, an ability to predict these storms has considerable value. We have recently come to understand that coronal mass ejections (CMEs) cause most large geomagnetic storms during the most active part of the solar cycle [Gosling et al., 1991].

Space Weather, Volume 24, Issue 3, March 2026.Abstract Space weather results in risks to gas pipelines in the form of both hazardous levels of pipe‐to‐soil potentials during extreme geomagnetic storms, and accumulated corrosion through less severe, but continuous geomagnetic activity. Here we report on calculations of pipe‐to‐soil potentials during a simulated extreme storm, using both direct ...

Interplanetary field and plasma during initial phase of geomagnetic storms [PDF]
Twenty-three geomagnetic storm events during 1966 to 1970 were studied by using simultaneous interplanetary magnetic field and plasma parameters. Explorer 33 and 35 field and plasma data were analyzed on large-scale (hourly) and small-scale (3 min ...

ED‐Autoformer: A New Model for Precise Global TEC Forecast
Space WeatherTotal electron content (TEC) is a key parameter for characterizing ionospheric morphology and significantly impacts the Global Navigation Satellite System. The ionosphere responds dramatically to solar and geomagnetic activity, leading to substantial TEC

Forecast of Ionospheric TEC Maps Using ConvGRU Deep Learning Over China
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingIn this article, we propose a convolutional gated recurrent unit (ConvGRU) deep learning method to forecast ionospheric total electron content (TEC) over China based on the regional ionospheric maps (RIMs) from 2015 to 2018.

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract 10Be deposition in ice cores is widely used for solar reconstructions, but its interpretation is complicated by volcanic influences. Using the state‐of‐the‐art aerosol‐climate model ECHAM6.3‐HAM2.3‐SALSA2.0: 10Be, we assess the impacts of three major volcanic eruptions: Agung (1963), El Chichón (1982) and Pinatubo (1991). All eruptions enhance
