Estimation of Arctic polar vortex ozone loss during the winter of 1999/2000 using vortex-averaged airborne differential absorption lidar ozone measurements referenced to N2O isopleths
The NASA Langley UV differential absorption lidar (DIAL) system flew on the NASA DC-8 aircraft during the Stratospheric Aerosol and Gas Experiment (SAGE) III Ozone Loss and Validation Experiment/Third European Stratospheric Experiment on Ozone 2000 (SOLVE/THESEO 2000) mission from 30 November 1999 t...
