Climate impact of idealized winter polar mesospheric and stratospheric ozone losses as caused by energetic particle precipitation
Energetic particles enter the polar atmosphere and enhance the production of nitrogen oxides and hydrogen oxides in the winter stratosphere and mesosphere. Both components are powerful ozone destroyers. Recently, it has been inferred from observations that the direct effect of energetic particle pre...
