A Regional 3‐D Data Assimilation Model for the Ionospheric Electron Density at Middle‐to‐High Latitudes in the Northern Hemisphere

Space Weather, Volume 23, Issue 5, May 2025.
Abstract In this paper, we developed an efficient regional three‐dimensional data assimilation model focused on the middle‐to‐high latitude ionosphere in the Northern Hemisphere. The model employed the Empirical Canadian High Arctic Ionospheric Model (E‐CHAIM) as the background, which was specifically optimized for high‐latitude applications and has ...

Empirical Functions for Highly Charged Ion Abundances in Solar Wind Charge Exchange Models: Addressing Post‐2011 ACE Data Limitations

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Upcoming imaging missions—NASA's LEXI and ESA/CAS's SMILE—will target solar wind charge exchange X‐ray (SWCX) emission from Earth's magnetosheath. This emission is generated by highly charged ions colliding with neutrals in Earth's exosphere.

The Influence of the Stretch of Mini‐Magnetospheres Formed by Crustal Fields on the Martian Bow Shock Location

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Mars lacks an intrinsic dipolar magnetic field but possesses strong crustal magnetic fields scattered across its surface. There has been an ongoing debate about how these crustal fields influence the bow shock, the outermost plasma boundary of the Martian space environment.

A Novel Model for Forecasting Geomagnetic Indices Using Machine Learning

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Widely used geomagnetic activity indices like Kp or Dst, derived from the combined data from several observatories distributed worldwide, are crucial to forecasting since solar‐driven geomagnetic activity can significantly affect technology and human activities on Earth and in near‐Earth space.

Magnetic field sector structure and origins of solar wind streams in 2012

Journal of Space Weather and Space Climate, 2014
The origins of the solar wind and the interplanetary magnetic field sector structure in the beginning of the magnetic polarity reversal of 24th solar cycle were investigated using the Wilcox Solar Observatory magnetic field measurements and their ...
