Scientific focus:

In recent years, many new satellite instruments capable of polar measurements have been launched. This has given unique opportunities to study effects of particle precipitation in the middle atmosphere.

The workshop is focused on the observational as well as modelling studies of atmospheric and ionospheric changes caused by energetic particle precipitation, e.g. solar proton events, relativistic electron precipitation, and auroral electron precipitation. Topics ranging from short-term ionospheric changes to long-term atmospheric changes are welcome, including defining spectra of precipitating particles and the effects on atmospheric dynamics.
