Multipoint Observations of Quasiperiodic Emission Intensification and Effects on Energetic Electron Precipitation
The two Van Allen Probes simultaneously recorded a coherently modulated quasiperiodic (QP) emission that persisted for 3 h. The magnetic field pulsation at the locations of the two satellites showed a substantial difference, and their frequencies were close to but did not exactly match the repetitio...

description | The two Van Allen Probes simultaneously recorded a coherently modulated quasiperiodic (QP) emission that persisted for 3 h. The magnetic field pulsation at the locations of the two satellites showed a substantial difference, and their frequencies were close to but did not exactly match the repetition frequency of QP emissions for most of the time, suggesting that those coherent QP emissions probably originated from a common source, which then propagated over a broad area in the magnetosphere. The QP emissions were amplified by local anisotropic electron distributions, and their large‐scale amplitudes were modulated by the plasma density. A novel observation of this event is that chorus waves at frequencies above QP emissions exhibit a strong correlation with QP emissions. Those chorus waves intensified when the QP emissions reach their peak frequency. This indicates that embryonic QP emissions may be critical for its own intensification as well as chorus waves under certain circumstances. A Low‐Earth‐Orbit POES satellite observed enhanced energetic electron precipitation in conjunction with the Van Allen Probes, providing direct evidence that QP emissions precipitate energetic electrons into the atmosphere. This scenario is quantitatively confirmed by our quasilinear diffusion simulation results.
Plain Language Summary
Quasiperiodic (QP) emissions in the near‐Earth magnetized space are electromagnetic waves in the audible frequency range. They propagate roughly along the magnetic field lines, and early scientists had received them simultaneously at the conjugate stations at Antarctica and Quebec. We report an interesting event in which the two NASA‐Van Allen Probes, with a separation of ∼7,000–12,000 km, simultaneously measured QP emissions that were identical in structure for over 3 h. We report a novel observation that another wave at a higher frequency, known as chorus waves, grows and exhibits a strong correlation with these QP emissions. A POES satellite that was in the Low‐Earth‐Orbit but roughly in the same magnetic field line as one of the Van Allen Probes detected enhanced precipitation of energetic electrons. This provides a direct evidence that QP emissions can effectively precipitate energetic electrons into the atmosphere. This scenario is confirmed by our numerical simulations.
Key Points
Quasiperiodic (QP) emissions observed by two Van Allen Probes remain coherent over a large spatial scale for 3 h

Quasiperiodic (QP) emissions observed by two Van Allen Probes remain coherent over a large spatial scale for 3 h
Chorus waves grow at frequencies above QP emissions and pause at gaps between QP emissions
Energetic electron precipitation in association with QP emissions is detected by conjugate observations at LEO and verified by simulations</abstract><cop>United States</cop><pub>American Geophysical Union (AGU)</pub><doi>10.1029/2020JA028484</doi><tpages>14</tpages><orcidid>https://orcid.org/0000-0003-3126-4394</orcidid><orcidid>https://orcid.org/0000-0001-8630-8054</orcidid><orcidid>https://orcid.org/0000-0003-0500-1056</orcidid><orcidid>https://orcid.org/0000-0002-0564-0440</orcidid><orcidid>https://orcid.org/0000-0001-8811-8836</orcidid><orcidid>https://orcid.org/0000-0003-2507-8632</orcidid><orcidid>https://orcid.org/0000-0002-6817-1039</orcidid><orcidid>https://orcid.org/0000-0003-3495-4550</orcidid><orcidid>https://orcid.org/0000-0001-7439-4362</orcidid><orcidid>https://orcid.org/0000-0002-5471-6202</orcidid><orcidid>https://orcid.org/0000-0001-6331-497X</orcidid><orcidid>https://orcid.org/0000-0002-7985-8098</orcidid><orcidid>https://orcid.org/0000-0003-3144-6542</orcidid><orcidid>https://orcid.org/0000-0002-2526-2205</orcidid><orcidid>https://orcid.org/0000-0001-5909-0926</orcidid><orcidid>https://orcid.org/0000-0001-9200-9878</orcidid><orcidid>https://orcid.org/0000-0003-1743-4262</orcidid><orcidid>https://orcid.org/000000016331497X</orcidid><orcidid>https://orcid.org/0000000331264394</orcidid><orcidid>https://orcid.org/0000000192009878</orcidid><orcidid>https://orcid.org/0000000186308054</orcidid><orcidid>https://orcid.org/0000000205640440</orcidid><orcidid>https://orcid.org/0000000188118836</orcidid><orcidid>https://orcid.org/0000000279858098</orcidid><orcidid>https://orcid.org/0000000334954550</orcidid><orcidid>https://orcid.org/0000000159090926</orcidid><orcidid>https://orcid.org/0000000254716202</orcidid><orcidid>https://orcid.org/0000000325078632</orcidid><orcidid>https://orcid.org/0000000331446542</orcidid><orcidid>https://orcid.org/0000000317434262</orcidid><orcidid>https://orcid.org/0000000225262205</orcidid><orcidid>https://orcid.org/0000000174394362</orcidid><orcidid>https://orcid.org/0000000305001056</orcidid><orcidid>https://orcid.org/0000000268171039</orcidid><oa>free_for_read</oa></addata></record> |
