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.

Changing Luminosity in Saturn’s Rings

Kudo to Crow Shannon, a co-author in a recent study published in Icarus about the changing luminosity of Saturn’s F ring. This exciting research story was recently reported in the LA Times. You can read the article here.

OK Shannon now it is time to go back to the chaos at Echo Base ;-)
