Canadian SciSat Finds a Delay in Ozone Recovery


from The Globe and Mail: Ozone-destroying chemical making comeback


Good news, bad news:


bad news: changes in circulation are causing “old” air with high levels of ozone-destroying hydrogen chloride to persist in the stratosphere, slowing ozone recovery due to CFCs.


good news: the Canadian SCISAT made the measurements that enabled this study, yet another success from this mission. Congratulations to Profs. Kaley Walker, Tom McElroy, Peter Bernath and the SCISAT team.
