That's a good question. PEARL is quite useful as a site for testing instruments, particularly under fairly harsh conditions. For example, we have been testing solar panels for a Canadian solar panel company. They're very interested in seeing how well they perform, and will then perhaps deploy them elsewhere in northern Canada.
One thing we helped do was evaluate the performance of an infrared instrument that will be deployed on Canada's HAWC mission, which I mentioned earlier. This is Canada's contribution to the atmosphere observing system that NASA will be launching later this decade. LR Tech and ABB developed this technology. We had it at Eureka. We had it side by side with an instrument that's been there for a longer term. We did side-by-side measurements to evaluate the performance of that instrument and prove that it would be able to do the kind of cloud measurements that we want to do from space. That's been very useful. That instrument is now being actively developed for deployment on a satellite later this decade.
