F2 region maximum electron density height predictions for South American latitudes [PDF]

, 2003
Values of the F2 region maximum electron density height (hmF2) calculated using ground ionosonde data at South American latitudes are used to check the validity of the International Reference Ionosphere (IRI) to predict this variable.

Do Eclipse‐Induced Thermospheric TADs Originate From Above or Below?

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Solar eclipses generate significant wave activity in the Earth's upper atmosphere. The source region of eclipse‐induced Traveling Atmospheric Disturbances (TADs) in the upper thermosphere—particularly the relative contributions of gravity waves from the thermosphere itself versus the lower atmosphere—remains unknown. Using the Whole Atmosphere

Dataset of Quiet Space Weather Periods for Ionospheric Studies

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract The ionosphere is a dynamic environment regularly affected from above and from below. This study identifies periods within the years 2000–2023 when the impact from above, driven by space weather, was minimal. The quiet space weather periods have wide usage for two types of ionospheric studies. At first, studies of isolated space weather events

Evaluation of foF2 and hmF2 Parameters of IRI-2016 Model in Different Latitudes over China under High and Low Solar Activity Years

Remote Sensing, 2022
The height of the peak electron density (hmF2) and the critical frequency of the F2 layer (foF2) are very important in the research of ionospheric electrodynamics and high frequency (HF) wireless communication.

A Computationally Efficient Method for Deriving Instantaneous F2 Layer Peak Parameters From Climatological Maps and TEC Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract International Reference Ionosphere (IRI) and the Ionosphere‐Plasmasphere (IRI‐Plas) models describe monthly median ionospheric conditions. IRI‐Plas, unlike IRI, allows one to include instantaneous Total Electron Content observations (TEC) to adjust the median predictions. The standard IRI‐Plas generates monthly medians of foF2m, hmF2m and TECm
