Contrasting the responses of three different groundbased instruments to energetic electron precipitation
[1] In order to make best use of the opportunities provided by space missions such as the Radiation Belt Storm Probes, we determine the response of complementary subionospheric radiowave propagation measurements (VLF), riometer absorption measurements, cosmic noise absorption, and GPS-produced total electron content (vTEC) to different energetic electron precipitation (EEP). We model the relati...
متن کاملEnergetic electron precipitation during sawtooth injections
We present simultaneous riometer observations of cosmic noise absorption in the nightside and dawn-noon sectors during sawtooth particle injections during 18 April 2002. Energetic electron precipitation (>30 keV) is a feature of magnetospheric substorms and cosmic radio noise absorption acts as a proxy for qualitatively measuring this precipitation. This event provides an opportunity to compare...
متن کاملUse of POES SEM‐2 observations to examine radiation belt dynamics and energetic electron precipitation into the atmosphere
[1] The coupling of the Van Allen radiation belts to the Earth’s atmosphere through precipitating particles is an area of intense scientific interest. Currently, there are significant uncertainties surrounding the precipitating characteristics of medium energy electrons (>20 keV), and even more uncertainties for relativistic electrons. In this paper we examine roughly 10 years of measurements o...
متن کاملImpact of Energetic Electron Precipitation on the Upper Atmosphere: Nitric Monoxide
Received: October 20, 2016 Revised: March 07, 2017 Accepted: March 11, 2017 Abstract: Background: Nitric oxide concentration in the upper atmosphere is known to be highly dependent on the solar activity. It can be transported to the stratosphere by the atmospheric circulation. In the stratosphere it is responsible for the destruction of ozone and consequently stratospheric heating rates are aff...
متن کاملMissing driver in the Sun–Earth connection from energetic electron precipitation impacts mesospheric ozone
Energetic electron precipitation (EEP) from the Earth's outer radiation belt continuously affects the chemical composition of the polar mesosphere. EEP can contribute to catalytic ozone loss in the mesosphere through ionization and enhanced production of odd hydrogen. However, the long-term mesospheric ozone variability caused by EEP has not been quantified or confirmed to date. Here we show, u...
