Special Issue Information

Dear Colleagues,

The objective of this Special Issue is to assemble a coherent set of papers that provide recent advances in the field of pulsating aurora investigation. Pulsating aurora (PsA) is a type of high-latitude atmospheric luminescence stimulated by energetic electrons with quasiperiodic local changes in emission amplitude. Recent advances in aurora observations by satellite missions and ground-based cameras with a high temporal resolution produce a detailed recording of the temporal and spatial structure of pulsating patches. Measurements of magnetospheric waves and charged particle flux provide an understanding of the close relation between energetic electron flux modulation, the structure of the chorus waves packets and the fine temporal structure of aurora emissions. Simulations demonstrate that microbursts of relativistic electrons arise during the interaction of chorus waves with particles, and these microbursts are the high-energy tail of pulsating aurora electrons. Recent experimental studies demonstrate a strong correlation between relativistic electron microbursts and some types of PsA. Precipitations of electrons with energies ranging from a few hundred kiloelectronvolts (keV) to a few megaelectronvolts (MeV) during PsA were observed. These precipitations lead to an increased ionization of the atmosphere at much lower altitudes than usual aurora. Nevertheless, the origin of PsA is still an open question, and further detailed measurements using joint ground-based and satellite measurements are needed. These and other intriguing questions and problems as well as recent theoretical and experimental progress are expected to be covered by this Special Issue.

Authors are encouraged to submit original papers that include, but are not limited to, topics of observations, modeling, instrumentation, etc. Review papers are also welcome.

We present the results of a systematic study of the ionospheric electric field in the Auroral Oval (AO) region in the southern hemisphere. We exploit one year of electric field measurements taken by the Electric Field Detector (EFD) on board the Chinese Seismo-Electromagnetic Satellite-01 (CSES-01), flying at around 500 km altitude in a sun-synchronous orbit. We exploit the high temporal resolution of the EFD to devise a new technique for the detection of CSES-01 crossing of the AO using electric field measurements only. This new technique combines a Median-Weighted Local Variance Measure with Fast Iterative Filtering to automatically isolate high levels of electromagnetic activity caused by, e.g., particle precipitation and Field Aligned Currents (FACs) at auroral latitudes. We validate this new method against other standard proxies, such as the single-FAC product from the Swarm mission and the auroral radiance emission measured by the Special Sensor Ultraviolet Spectrographic Imager (SSUSI) units on board the Defense Meteorological Satellite Program (DMSP) constellation. Furthermore, we identify ∼3000 orbits (out of a dataset of ∼10,000) where CSES-01 crosses the AO boundary under conditions of high geomagnetic activity. This dataset represents the first step in the systematic study of the auroral electric field, with many potential applications to space weather, thanks to the large amount of continuous observations of the ionosphere by CSES-01 and the forthcoming CSES-02 mission.

Tracking Ultraviolet Set-up (TUS) on board the Lomonosov satellite measured the UV intensity pulsations in the auroral region. Sixty-four events with pulsations were registered during two measurement periods from 26 December 2016–10 January 2017 and 8–15 November 2017. During both periods, a high-intensity, long-duration, continuous auroral activity (HILDCAA) was detected. Simultaneous measurements in LEO by Lomonosov (DEPRON detector) and Meteor-M2 satellites show the enhanced fluxes of the trapped and precipitated energetic electrons in the region of the Earth’s outer radiation belt during these periods. We found that most of the UV-events correspond to energetic electron (E > 100 keV) precipitation. One can suggest that particles of these and higher energies cause a pulsating emission relatively deep in the atmosphere. Full article
