To say we don't plan to merge two networks would not exactly be precise.
We plan to continue to use both methods. Both methods are needed. Both methods will continue to be used. You can go to our website and see a map where we measure ozone. You will see that in most sites we're measuring using both the Brewer and the ozonesonde methods. In some sites we only use the Brewer and in some sites we only use the ozonesonde. The discussion point for scientists is whether we need all sites. Do we need to use Brewer and ozonesonde at all sites? We don't currently.
There is also a potential for streamlined management. To a large extent we've had one network that's been referred to as the Brewer network and another one that's been referred to as the ozonesonde network.
A science plan published by the branch in 2007 gave a good vision of more integrated monitoring. You will see that as a consistent theme throughout the work of my branch, to have more integrated monitoring to increase our assurance that we are optimizing our use of different methodologies so that folks are always talking about what results we are getting with this method and what it means for another method. We're looking both at the scientific management and the data management to see if we can have some efficiency gains.
