HAO Research Highlights

GOCE neutral density on dusk side
September 4, 2018

Some recent studies have revealed that the post-storm thermospheric mass density sometime drops below its pre-storm value. This phenomenon has been attributed to the over-cooling effect caused by enhanced infrared emissions from nitric oxide.

COSMIC GPS radio occultation observations
August 28, 2018

Medium-scale ionospheric ionization structures are a persistent global feature of the earth’s ionosphere.

Amplitudes of the Q6DW as a function of latitude and time
August 25, 2018

This study, by Pedatella and others, employs a troposphere to lower thermosphere reanalysis dataset generated by the Whole Atmosphere Community Climate Model with data assimilation provided by the Data Assimilation Research Testbed (WACCM+DART).

MGITM-calculated horizontal distributions
August 24, 2018

Wang and others present a global, time-dependent simulation of the Mars upper atmospheric responses to an X8.2-class solar flare event on 10 September 2017.

Painting the dips of a magnetic skeleton results in sheet-like prominences
August 24, 2018

Magnetic fields suspend the relatively cool material of solar prominences in an otherwise hot corona. A comprehensive understanding of solar prominences ultimately requires complex and dynamic models, constrained and validated by observations spanning the solar atmosphere.
