Monday, June 5, 2017

In order to calculate the Earth’s whole atmosphere and ionosphere coupled system in a self-consistent way, new ionosphere and electrodynamo modules have been implemented in the thermosphere and ionosphere eXtension of WACCM-X. WACCX-X stands for the Whole Atmosphere Community Climate Model.

Variability and predictability of the space environment as related to lower atmosphere forcing

Most of the large events affecting the thermosphere and ionosphere part of the space environment come from the Sun, the solar wind, and Earth’s magnetosphere.

This book chapter describes the basic physical processes in the thermosphere, or Earth's neutral upper atmosphere, which need to be captured in a physics-based model. Liu, H., 2014: WACCM-X simulation of tidal and planetary wave variability in the upper atmosphere.

Large Scale Gravity Waves Perturbations in Mesopause Region

Wednesday, November 23, 2016

To investigate the Gravity Wave (GW) in the mid-latitude mesopause region during boreal equinox, 433 hours of continuous full diurnal cycle temperature measurements in September between 2011 and 2015.

Fabry-Perot Interferometers

CISM_DX

CISM_DX is a community-developed suite of integrated data, models, and data and model explorers, for research and education. The data and model explorers are based on code written for OpenDX and Octave.

LYON-FEDDER-MOBARRY (LFM) GLOBAL MHD CODE

The LFM Code is an integrated simulation model for the global magnetosphere-ionosphere system. The heart of the model is a time-dependent, ideal MHD calculation of the state of the magnetosphere.

Driving magnetosphere-ionosphere coupling in upper-atmosphere models with observed field-aligned currents from the AMPERE mission

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).

Dependence of solar-wind/magnetosphere/ionosphere coupling on the geomagnetic dipole strength

Friday, November 2, 2012

The possible effects of geomagnetic-field changes over periods of millennia on solar wind/magnetosphere/ionosphere/thermosphere coupling was examined, by altering the strength of the geomagnetic dipole in the Coupled Magnetosphere-Ionosphere-Thermosphere (CMIT) model.
