00:10This is the first time two hours passed.
00:11The new one for two hours is clearance.
00:12The new one is the final part.
00:13It is a beautiful process.
00:20And it is a new design by which I am going to be very simple.
00:29I'm sorry.
00:34I got a hand and I'm not going to have the hot seat.
00:41I'm sorry.
00:43I'm sorry.
00:45I'm sorry.
00:48I'm sorry.
00:51I'm sorry.
00:55I think I'm sorry.
01:01Do the other way, the red check.
01:03Remember, they can go down this way.
01:11You're allowed.
01:14I'm still allowed.
01:18You're living for it, you're living for it.
01:28So SABR is a project to study the processes that regulate aerosol in the stratosphere,
01:37which has a climate effect.
01:39So aerosol in the stratosphere acts to reflect sunlight back to space and is not particularly
01:47well understood because it's so hard to do science in the stratosphere.
01:52From Panama we can fly west into the Pacific, we can fly south and get into the southern
01:57hemisphere, we can fly northeast over the Caribbean and see air that's been transported
02:00all the way from Africa and Asia, as well as studying the really intense convection that
02:06occurs over both northern South America and Central America.
02:12What we want to do is we can make some measurements that will tell us whether the Earth is really
02:16responding the way the models think it should be, as well as understanding how various changes
02:24that might occur to the stratosphere due to climate change will then feed back into the
02:30climate system.
02:31If you have more fires, you might get more smoke particles, and how does that affect both transport
02:38phenomenons or how air moves through, as well as chemistry that affects things like the ozone
02:43layer.
02:44Yeah, at 61,000 feet you're roughly twice as high as a commercial airliner, so most people
02:51are familiar with looking out the window at 30,000 feet.
02:54And it's a similar picture, but the sky is darker, and you're starting to see a bit of curvature
03:01on the Earth.
03:03You can actually see kind of the Earth falling away from you.
03:08And it's quite beautiful to see a sunset or a sunrise up there.
03:13You can't see it.
03:14That's the end of the day.
