Space Weather, Volume 23, Issue 10, October 2025.Abstract Using observations from the National Space Weather Laboratory's (LANCE acronym in Spanish) ground‐based network, we characterize regional space weather conditions in Mexico during the solar minimum 24/25 (2018–2020). Data analyzed include regional geomagnetic indices (the regional K index, Kmex, and Δ ${\Delta }$H), ionospheric Total Electron ...

Impacts of the May 2024 Extreme Geomagnetic Storm on Global High‐Accuracy GPS Positioning Solutions
Space Weather, Volume 23, Issue 10, October 2025.Abstract The May 2024 geomagnetic storm has been recognized as the most severe one in the past two decades and was categorized as an “extreme” (G5) event according to the NOAA space weather scales. This study applies Precise Point Positioning (PPP) software PRIDE PPP‐AR to over 5,800 worldwide GNSS receiver data to highlight the vulnerability of high ...

Asymmetries in the Temporal Variation of the Electron Content During a Solar Eclipse
Earth and Space Science, Volume 12, Issue 7, July 2025.Abstract Solar eclipses offer a unique opportunity to study rapid variations in the Earth's atmosphere. By accurately modeling the timing and magnitude of obscuration caused by the Moon's shadow, we can investigate the eclipse's impact on the behavior of the Earth's ionosphere.

Space Weather, Volume 23, Issue 4, April 2025.Abstract The space weather event on 10–11 May 2024 was a high‐impact geomagnetic storm, resulting in a SYM‐H index decrease to −518 nT, the lowest level registered in several decades. We investigated the response of the Earth's ionosphere during the main phase of this storm using a comprehensive data set of ionospheric observations (in situ plasma ...

Journal of Geophysical Research: Space Physics, Volume 130, Issue 3, March 2025.Abstract Deep convective clouds and lightning activity during thunderstorms imprint Infrasonic (> ${ >} $3 mili Hertz) oscillations in the ionospheric density or Traveling Ionospheric Disturbances (TIDs). The wave characteristics of these oscillations and the coupling mechanisms remain a subject of investigation, noting that the coupling energetics may
