Ionospheric Electron Content during Solar Cycle 23

Comparison of measured to modeled global total electron content
Tuesday, March 13, 2018

Solomon & Qian show that solar minima are not all the same, and may have implications for understanding the Sun during the extended periods of very low activity known as “grand minima” that have sometimes occurred in the past, the best known of which was the Maunder Minimum during 1650–1700.

Simulation of the August 21, 2017 Solar Eclipse using the Whole Atmosphere Community Climate Model—eXtended

Temperature differences between the eclipse and baseline simulations
Wednesday, February 7, 2018

Joseph McInerney and others, use a computer model called the Whole Atmosphere Community Climate Model - eXtended (WACCM-X v. 2.0) to investigate what happens to the atmosphere from the surface of Earth up to space during the “Great American Eclipse” of 21 August 2017.

Whole Atmosphere Simulation of Anthropogenic Climate Change

Model calculations
Friday, February 2, 2018

Stan Solomon and others have performed the first whole-atmosphere simulations of global change that include the lower atmosphere (0-15 km), middle atmosphere (15-90 km), thermosphere-ionosphere (90-500 km), and all relevant physics and chemistry.

Liying Qian et al investigate atomic hydrogen (H) variability from the mesopause to the upper thermosphere, on time scales of solar cycle, seasonal, and diurnal.

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.

WACCM-X Extended Runs

10 TB of WACCM-X specified dynamics output, covering the years 2000-2014, are available on the NCAR Earth System Grid.

All data are in netCDF files: self-describing binary data format used for primary CESM output.

Friday, November 2, 2012

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.
