Space weather impact on mesospheric ozone



The mesosphere (50-100 km) forms part of the crucial interface between ground weather and space weather. It is known that particle precipitation into the auroral zone from space creates a long-lived nitrous-oxides compounds (NOx), which are a power catalyst for ozone destruction. Once created, NOx circulates with the winds destroying ozone far from the auroral zone.
We aim to:
(1) Determine in-situ ozone loss as a function of particle flux and energy
(2) Determine ozone gain as a function stratospheric warming events, and
(3) Determine ozone loss due to nitrous-oxide circulation.
