HALO mission integration ongoing

Preparations for the next HALO mission are on the way. During the ASCCI campaign, scientists aim at improving their understanding of:

1. Inter-annual variability of Arctic lower stratospheric ozone depletion and the implications for radiative forcing and surface climate impacts of ozone recovery
2. High latitude stratosphere-troposphere exchange and the structure of the high latitude tropopause
3. Short-lived climate pollutants (ozone, aerosols) and their precursors in the Arctic mid and upper troposphere
