Availability of far ultraviolet observations of Earth’s dayglow by the NASA Global-scale Observations of the Limb and Disk (GOLD) mission presents an unparalleled opportunity for upper atmosphere radiance data assimilation.

The NASA Global-scale Observations of the Limb and Disk (GOLD) ultraviolet spectrograph began imaging the Equatorial Ionization Anomaly (EIA), regions of the ionosphere with enhanced electron density north and south of the magnetic equator, in October 2018.

The second Miniature X-ray Solar Spectrometer (MinXSS-2) CubeSat builds on the success of MinXSS-1. The science instrument is more advanced – now capable of greater dynamic range with higher energy resolution.

Solomon and colleagues conducted global simulations of temperature change due to emissions of trace gases due to human activity, that extended from the surface, throughout the atmosphere, to space.

In a recent work, we found that, in the mesosphere and lower thermosphere (MLT) region at middle latitudes, adiabatic heating/cooling and vertical heat advection, both associated with vertical wind changes, are the dominant processes that determine the temperature responses to storms.

To address challenges of assessing capabilities of space weather modeling, the CCMC (Community Coordinated Modeling Center) is leading a newly established “International Forum for Space Weather Modeling Capabilities Assessment.”

The specification and prediction of density changes in the thermosphere is a key challenge for space weather observations and modeling, because it is one result of complex interactions between the Sun and the terrestrial atmosphere, and also because it is of operational importance for tracking ob

Solar irradiance models indicate that irradiance variations are dominated by changes in disk-coverage of magnetic structures, whose brightness is thought to be determined by their size and average magnetic flux density.

Stan Solomon et al, dicuss a new modeling capability that self-consistently couples physics-based magnetospheric 18 electron precipitation with its impact on the ionosphere, representing a significant improvement over previous models.
