Precipitating auroral and radiation belt electrons are considered an important part of the
natural forcing of the climate system. Recent studies suggest that this forcing is …

Sudden stratospheric warmings (SSWs) are circulation anomalies in the polar region during
winter. They mostly occur in the Northern Hemisphere and affect also surface weather and …

Sudden stratospheric warming (SSW) events are large-scale dynamic phenomena which
can significantly affect the circulation, temperature, and composition of different atmospheric …

Precipitation in the upper atmosphere of energetic radiation belt electrons leads to a number
of secondary effects, including the production of new ionization, emission of X-rays via …

This study considers the impact of electron precipitation from Earth's radiation belts on
atmospheric composition using observations from the NASA Van Allen Probes and NSF …

Using simulations with a whole-atmosphere chemistry-climate model nudged by
meteorological analyses, global satellite observations of nitrogen oxide (NO) and water …

Abstract The Atmospheric Effects of Precipitation through Energetic X-rays (AEPEX) mission
is a 6U CubeSat that will monitor energetic electron precipitation from the radiation belts into …

The vertical coupling between the stratosphere and the mesosphere is diagnosed from polar
cap temperatures averaged over 60°–90° N with a new method: the joint occurrence of a …

The energetic particle precipitation (EPP) indirect effect (IE) refers to the downward transport
of reactive odd nitrogen (NOx= NO+ NO2) produced by EPP (EPP‐NOx) from the polar …

Abstract Stratospheric Sudden Warmings (SSWs) followed by the formation of an elevated
stratopause at~ 70–80 km occurred in four of the five recent Arctic winters (2009–2013). We …
