Geomagnetic field-aligned currents from the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE) satellite mission are used to drive the Thermosphere-Ionosphere-Electrodynamics General Circulation Model (TIEGCM).

An analysis was done of the momentum budget of the diurnal westward-propagating wavenumber-1 (DW1) tide simulated by the Whole Atmosphere Community Climate Model (WACCM).

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.

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.
