Airborne Lidar Observations of Ozone in the Arctic Winter 1994/95

摘要

Measurements with an airborne lidar in the Arctic winter 1994/95 show that the ozone mixing ratio declined by about 50percent through-out the polar vortex in the period from the beginning of February to mid of March in a sharp defined altitude band from 420 K to 520 K potential temperature. The simultaneous detection of the stratospheric aerosol density provides evidnece that this depletion was not caused by dynamical processes but by chemical reactions.
