Article Synopsis
- Solar particle events (SPEs) are bursts of high-energy particles from the sun that can significantly affect the Earth's environment, posing economic risks, especially when the geomagnetic field is weak.
- Historic extreme SPEs can severely alter atmospheric chemistry, leading to ozone depletion and increased ground-level UV radiation, which can harm both the environment and human health.
- Modeling suggests that under current geomagnetic conditions, extreme SPEs could elevate NO levels and reduce ozone, while a complete lack of geomagnetic protection could cause widespread ozone damage for years, increasing solar-induced DNA damage rates significantly.
The understanding of forced temporal variations in celestial pole motion (CPM) could bring us significantly closer to meeting the accuracy goals pursued by the Global Geodetic Observing System (GGOS) of the International Association of Geodesy (IAG), i.e., 1 mm accuracy and 0.

This has led to the assertion that the geomagnetic field may be undergoing a reversal or an excursion. We have derived a model of the geomagnetic field spanning 30-50 ka, constructed to study the behavior of the two most recent excursions: the Laschamp and Mono Lake, centered at 41 and 34 ka, respectively.

While many studies tested the reliability of this recorder for palaeointensity only a few studies did this for direction. The study presents an archaeomagnetic and rock magnetic investigation applied to an experimental pottery kiln, which was operated in 2003 to produce stone ware.
