Precipitation of energetic particles into the atmosphere greatly disturbs the chemical
composition from the upper stratosphere to the lower thermosphere. Most important are …

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 …

While knowledge of the energy inputs from the Sun (as it is the primary energy source) is
important for understanding the solar-terrestrial system, of equal importance is the manner in …

We evaluate the influence of the galactic cosmic rays (GCR), solar proton events (SPE), and
energetic electron precipitation (EEP) on chemical composition of the atmosphere …

Abstract The past three years (2020–2022) have witnessed the re-emergence of large, long-
lived ozone holes over Antarctica. Understanding ozone variability remains of high …

Energetic particle precipitation couples the solar wind to the Earth's atmosphere and
indirectly to Earth's climate. Ionisation and dissociation increases, due to particle …

Here we use the ERA‐40 and ECMWF operational surface level air temperature data sets
from 1957 to 2006 to examine polar temperature variations during years with different levels …

The atmospheric chemistry general circulation model ECHAM5/MESSy is used to simulate
polar surface air temperature effects of geomagnetic activity variations. A transient model …

Energetic particle precipitation into the upper atmosphere creates excess amounts of odd
nitrogen and odd hydrogen. These destroy mesospheric and upper stratospheric ozone in …

We analyzed ERA‐40 and ERA Interim meteorological re‐analysis data for signatures of
geomagnetic activity in zonal mean zonal wind, temperature, and Eliassen‐Palm flux in the …
