Thermosphere

It's a Bird, it's a Plane, no, it's HiWIND

HiWind

In February, 2018, a specialized engineering team, led by principal investigator Dr. Qian Wu, traveled from Boulder, Colorado to a NASA facility in Palestine, Texas.

The longitudinal variations of upper thermospheric zonal winds observed by the CHAMP satellite at low and mid-latitudes

Longitudinal structures of zonal winds
Thursday, March 1, 2018

In this work, Kedeng Zhang, Wenbin Wang and others, investigate the longitudinal patterns of thermospheric zonal winds (~400 km) and their seasonal and solar activity dependence.

Faster Traveling Atmosphere Disturbances Caused by Polar Ionosphere Turbulence Heating

Meridional wind variability
Wednesday, February 28, 2018

For the first time, a new module enables Jing Liu and others to investigate the intimate coupling between polar turbulence electron heating and thermosphere disturbances in the context of a first principle, self-consistent model.

Analysis and Hindcast Experiments of the 2009 Sudden Stratospheric Warming in WACCMX+DART

Total electron content (TEC)
Thursday, December 7, 2017

Plain Language Summary or Abstract: Whole atmosphere models offer the opportunity to improve specification and forecasting of the upper atmosphere through incorporating the effects of forcing from both the lower atmosphere as well as the Sun.

Evidence of the Lower Thermospheric Winter to- Summer Circulation From SABER CO2

SD-WACCM mean fields
Thursday, November 2, 2017

Numerical studies have shown that there is a lower thermospheric winter-to-summer circulation that is driven by wave dissipation and that it plays a significant role in trace gas distributions in the mesosphere and lower thermosphere, and in the composition of the thermosphere.

The Global-Scale Observations of the Limb and Disk (GOLD) Mission

Simulation of GOLD atomic oxygen emissions
Monday, August 14, 2017

The NASA Global-scale Observations of the Limb and Disk (GOLD) mission is a dual-channel imaging spectrograph that will be carried on a commercial communications satellite in geostationary orbit. Launch is scheduled for January, 2018.

Impact of the lower thermospheric winter-to-summer residual circulation on thermospheric composition

TIE-GCM simulated effects
Monday, June 12, 2017

Plain Language Summary or Abstract: Gravity wave forcing near the mesopause drives a summer-to-winter residual circulation in the mesosphere and a reversed, lower thermospheric winter-to-summer residual circulation.

The NASA Ionospheric Connection Explorer (ICON) Mission

Variation of NmF2 log 10 [1/cm3] for different seasons
Wednesday, April 26, 2017

The NASA Ionospheric Connection explorer (ICON) will study the coupling between the thermosphere and ionosphere at low- and mid-latitudes by measuring the key parameters.

Effects of Magnetospheric Lobe Cell Convection on Dayside Upper Thermospheric Winds at High Latitudes

Average ionospheric potential and DMSP F-16 ion drift observations
Tuesday, October 4, 2016

This paper investigates a possible physical mechanism of the observed dayside high-latitude upper thermospheric wind using numerical simulations from the coupled magnetosphere-ionosphere-thermosphere (CMIT) model.
