Depletion of ozone and reservoir species of chlorine and nitrogen oxide in the lower Antarctic polar vortex measured from aircraft
Novel airborne in-situ measurements of inorganic chlorine, nitrogen oxide species and ozone were performed inside the lower Antarctic polar vortex and at its edge in September 2012. We focus on one flight during the TACTS/ESMVal campaign with the German research aircraft HALO, reaching latitudes of...
