Chemical ozone loss in the Arctic winter 1991-1992
Chemical ozone loss in winter 1991-1992 is recalculated based on observations of the HALOE satellite instrument, Version 19, ER-2 aircraft measurements and balloon data. HALOE satellite observations are shown to be reliable in the lower stratosphere below 400 K, at altitudes where the measurements a...
