Match observations in the Arctic winter 1996/97: High stratospheric ozone loss rates correlate with low temperatures deep inside the polar vortex

摘要: With the Match technique, which is based on coordinated release of ozonesondes, chemical ozone loss rates in Arctic stratospheric vortex early 1997 have been quantified a vertical region between 400 K and 550 K. Ozone destruction was observed from mid February to March most these levels, with maximum 25 45 ppbv/day. The averaged accumulated vertically integrated smaller than previous two winters, indicating that record low columns spring were partly caused by dynamical effects. inhomogeneous through highest located centre, coinciding lowest temperatures. Here per sunlit hour reached 6 ppbv/h, while corresponding did not exceed 3.9 ppbv/h.
