HAO Research Highlights

An overview of interesting vantage points, highlighting previous extra-Sun-Earth-line (extra-SEL) missions
July 26, 2018

We explore new opportunities for solar physics that could be realized by future missions providing sustained observations from vantage points away from the Sun-Earth line.

Nicholas Pedatella notes that geomagnetic storms are an important driver of variability in Earth’s ionosphere, and can have significant societal impacts through the ionosphere’s impact on communications and navigation systems (e.g., GPS).

New mechanisms for imposing planetary-wave (PW) variability on the ionosphere thermosphere system are discovered in numerical experiments conducted with the National Center for Atmospheric Research (NCAR) Thermosphere-Ionosphere- Electrodynamics General circulation Model (TIE-GCM).
