Thermospheric Density and Wind Response to Auroral Activity Observed by the Dissipation Sounding Rocket Mission
AGU 2024
spa-aeronomy | 13 december 2024
Diana Swanson, James H. Clemmons, Lance Davis, Meh...
The comingled ionosphere/thermosphere (IT) acts as the transition region between Earths atmosphere and space. Auroral precipitation flowing from the m...

Combining Time-Dependent Electron Transport Calculations with Rocket Measurements to Study Small-Scale Dynamic Precipitation
AGU 2024
spa-aeronomy | 13 december 2024
Etienne Gavazzi, Andres Spicher, Björn Gustavsson,...
Dynamic, small-scale auroras are commonly associated with Alfven waves. The waves travel along magnetic field lines and accelerate electrons downward ...

Measurements from the Dissipation Auroral Sounding Rocket Mission: Estimates of the Interactions between Precipitating Electrons and the Thermosphere
AGU 2024
spa-aeronomy | 13 december 2024
Lance Davis, James H. Clemmons, Diana Swanson, Meh...
Electron precipitation into the upper atmosphere strongly affects the ionization rate in the thermosphere-ionosphere region, thereby heavily influenci...

Electron measurements from the Beam-PIE sounding rocket: a comparison of two pitch-angles
AGU 2024
spa-aeronomy | 12 december 2024
Robert Michell, Marilia Samara, Emma R. Mirizio, E...
The Beam-PIE sounding rocket launched from Poker Flat, AK and passed through a weak auroral event in November 2023. We present electron measurements m...

The Impact of Independently Derived Neutral Winds on Ionospheric Frictional Heating
AGU 2024
spa-aeronomy | 11 december 2024
Andrew Pepper, Stephen R. Kaeppler, Miguel F. Lars...
The closure of field-aligned currents in the E-region ionosphere is caused by ion-neutral collisions which enable ions to drift perpendicular to the m...

Extremely Large Plasma Drifts in the High-Latitude Ionosphere
AGU 2024
spa-aeronomy | 11 december 2024
Harri E. Laakso, Robert F. Pfaff
We have recently reported about ~200 fast flow events above 5 km/s in the high-latitude ionosphere measured by the vector electric field double probe ...
