Data sets

MLS/Aura Level 2 Ozone (O3) Mixing Ratio V003, version 003 from Goddard Earth Sciences Data and Information Services Center (GES DISC), Greenbelt, MD, USA EOS MLS Science Team

The Sodankylä ozonesonde data in the NDACC database NDACC

Short summary
Atmospheric ozone concentrations above Kiruna, Sweden, within 16–54 km altitude, were obtained using measurements from two ground-based instruments, KIMRA and MIRA 2. The results were compared to satellite and balloon data for validation, revealing an oscillatory offset in KIMRA data between 18 and 35 km. KIMRA data from 2008 to 2013 show a local minimum in mid-stratospheric winter ozone concentrations that is likely due to dynamics related to the polar vortex.
