It has long been recognized that during solar eclipses, the ionosphere-thermosphere system changes greatly within the eclipse shadow, due to the rapid reduction of solar irradiation.

The high-resolution thermosphere-ionosphere-electrodynamics general circulation model (TIEGCM) was used to investigate the cause of F2-region electron density (Ne) responses to the Great American Solar Eclipse on 21 August 2017 at Millstone Hill (42.610N, 71.480W).

Faster Traveling Atmosphere Disturbances Caused by Polar Ionosphere Turbulence Heating

H.Liu et al. have improved a comprehensive numerical model, the Whole Atmosphere Community Climate Model with thermosphere and ionosphere extension (WACCM-X).

Grand Challenge Research on Subauroral Polarization Streams

Joule heating of the ionosphere simulated by the NCAR TIE-GCM

A team from the NCAR High Altitude Observatory, Johns Hopkins University, and Rice University, led by HAO scientist Wenbin Wang, was awarded a prestigious NASA Heliophysics Grand Challenge Research Grant to study the magnetosphere-ionosphere interaction known as subauroral polarization streams.

Impact of high-speed streams and co-rotating interaction regions on the thermosphere-ionosphere

Changes in the thermosphere-ionosphere system caused by high-speed streams in the solar wind, and the co-rotating interaction regions they engender, were studied using a combination of CMIT and TIEGCM simulations and data analysis. 

Global ionospheric climatology

NmF2 climatology for 2007 to 2010 in magnetic latitude bins image
Friday, November 2, 2012

Extensive analyses of COSMIC data for 2007–2010 have revealed a number of features concerning seasonal and solar-cycle variation. Low-latitude ionospheric peak density NmF2 was dominated by the semi-annual anomaly, the equatorial anomaly and the annual asymmetry.
