Certainly.
In a memo to the minister, absolutely, I indicated that the measurements are complementary and do not duplicate each other. That's in the context of each method of measurement.
The Brewer instrument is required to validate or verify the information we get from satellites. The scientists don't yet have the degree of precision with the satellite data unless they can verify it against the data from the Brewer. With the ozonesondes, again we're looking at different methods. The same briefing note indicated that we would be looking to optimize our utilization of the two methods across Canada, so that our overall measurement and monitoring of ozone would be optimized, and not the use of one method, nor use of a different method, but both methods in combination.
