Environment committee  —having a research scientist whose only focus is ozone. He's in my branch, and he is in Dr. Lin's area.

Environment committee  But yes or no is not an appropriate answer. Where they're assigned, ozone is part of an air quality issue—

Environment committee  Right. So again, we have scientists who study ozone, and they remain within Environment Canada.

Environment committee  Yes.

Environment committee  The science and technology branch has an important role to play in this, but we're not the policy setters and we're not the regulator. But when you monitor something, attention gets paid to it, and people need to respond to what the monitoring is showing. A good example of that

Environment committee  Yes.

Environment committee  Yes.

Environment committee  Yes, I do. I want to just explain a little bit or elaborate a little bit on Environment Canada's role and academia's role. When it comes to long-term monitoring of something, that seldom gets research grants from the large research-granting councils either at the federal level

Environment committee  Yes.

Environment committee  Thank you. I'm happy to do so. In terms of the scientific oversight from science and technology branch, that continues, and we have research scientists whose expertise is in ozone and in the data related to ozone in the atmosphere. An immense amount of data is collected by ou

Environment committee  The individual scientists you have maybe heard from may not be representative of the general community. Certainly some of my staff met with the scientific advisory group at the end of the summer. Just last week I was in Geneva and met with the individuals at the World Meteorolog

Environment committee  As far as I know, apart from the discussion at the scientific advisory group, we certainly haven't received any direct criticisms. I don't know, Charles, whether you've had letters in. Again, the scientific advisory group would be the world's congregation of those who are cons

Environment committee  The use of the Brewer spectrophotometer is, if anything, continuing to increase in other countries around the world, with others recognizing the advantages that the Brewer instrument can offer. I think we still have an excellent reputation there. Our role in using the Brewer tria

Environment committee  Thanks. I'll start, and then my colleague, Dr. Charles Lin, may add, since he's even closer to the science than I am. If you consider the issue of ozone depleting substances, when action was taken under the Montreal protocol, there were predictions that it would take quite a lon

Environment committee  Again, the LiDAR is a technology, it is not what are you studying with the technology. Environment Canada has a number of LiDARs. We maintain that kind of capability. Without getting too technical, the LiDAR can detect different kinds of particles and chemicals in the atmospher
