Large-Scale Traveling Atmospheric and Ionospheric Disturbances Observed in GUVI With Multi-Instrument Validations

This study presents multi-instrument observations of persistent large-scale traveling ionosphere/atmospheric disturbances (LSTIDs/LSTADs) observed during moderately increased auroral electrojet activity and a sudden stratospheric warming in the polar winter hemisphere. The Global Ultraviolet Imager (GUVI), Gravity field and steady-state Ocean Circulation Explorer, Scanning Doppler Imaging Fabry–Perot Interferometers, and the Poker Flat Incoherent Scatter Radar are used to demonstrate the presence of LSTIDs/LSTADs between 1 ...

Observations of Spatial Variations in O/N ₂ During an Auroral Substorm Using the Multichannel Downlooking Camera on the VISIONS Rocket

At 0821 UT on 7 February 2013, during an auroral substorm, the NASA VISIONS rocket was launched northward from Poker Flat Research Range on a flight to approximately 750-km altitude that terminated in the Arctic Ocean. A subpayload jettisoned on the up leg carried a multichannel optical imager that looked downward and observed the auroral emission through four narrow passband filters. Three of the channels had sufficiently strong signal to allow a measure of the time evolution of the horizontal extent of the electron auro ...

Wind-driven transport of thermospheric air parcels in the auroral zone

Data from ground-based optical instruments at Poker Flat and Fort Yukon in Alaska recorded during 2010 were used to examine the relationship between composition changes in the auroral thermosphere and transport effects by neutral winds. Thermospheric column [O]/[N2] estimates were obtained from a pair of four-channel zenith-pointed narrow field photometers located at Poker Flat and Fort Yukon, whereas neutral winds at E and F-region heights were measured using an all-sky imaging Fabry-Perot spectrometer at Poker Flat. Wind f ...
