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 atmosphere. You can put it to different uses. Right now, we're most interested in two things using LiDARs. One is looking at the long-range transportation of air pollutants. We have one at Whistler that looks to see whether we are receiving air pollutants from others around the world. Another one or two we are looking to deploy—I'm not sure if they are there yet—to the oil sands to support us in the work we are doing in monitoring different contaminants in the atmosphere of interest with respect to oil sands development.
