Environment committee  That is correct. In terms of the ARQX organizational changes, what I did not mention was that the manager resigned—left for, shall we say, greener pastures, for personal reasons—and also a senior research scientist left as well. So it's not like we are laying off people and red

Environment committee  Yes. The oversight function for the ozone data centre, the capacity to do ozone science, still remains within Environment Canada.

Environment committee  The answer would be yes and no. I'll explain. ARQX was part of air quality, so it is not a question of taking a group that was outside of air quality and putting that into air quality.

Environment committee  The people have moved into two divisions, into modelling and monitoring.

Environment committee  The answer is no.

Environment committee  So it's yes and no: yes and no.

Environment committee  Perhaps I could jump in here.

Environment committee  There's significant variability. There are many factors that determine the distribution of ozone over the Arctic: the chemical reactions, the solar exposure, polar stratospheric clouds, the snow and ice distribution. These parameters change from year to year. It is a challenge to

Environment committee  If I may jump in here, for the scientific advisory group that Dr. Dodds mentioned, the last meeting came at the tail end of the Quadrennial Ozone Symposium, which is an international symposium held every four years that gathers all the ozone experts from around the world. The ann

Environment committee  Yes.

Environment committee  What I said was that Environment Canada still has significant capacity in ozone science. Now, we of course collaborate with many partners, including academia. That is true in ozone science and in other endeavours that we do.

Environment committee  Yes. One of the most famous observatories in the environmental field is Mauna Loa in Hawaii. There are two Brewers at Mauna Loa that are really Environment Canada Brewers. There's a sticker on them that says NOAA, but they are Environment Canada Brewers. Their function, in add

Environment committee  Yes. I can do that. The interaction between climate change and ozone is a complex story. Many of the players, in addition to reacting chemically with ozone, are also greenhouse gases themselves. There are two parallel stories going on. An active area of research is just to try t

Environment committee  The body will be transitioned to MSC because he has the experience of operating the centre. Then we will go to a different model, where MSC takes over the centre. This individual will help in the transition.

Environment committee  Yes. As I said earlier, the Met service has experience maintaining operational networks that report routinely and regularly on a consistent basis, and that data is used in near real-time. We've decided to put the ozone data centre, the WOUDC, under the auspices of the MSC. But at
