 So I'm an atmospheric scientist and when you think about the atmosphere you have to imagine the atmosphere is a number of layers. And if we think about the bottom layer, the troposphere, that's where we all live, it's where the weather occurs that we experience. That goes from about the ground to about 15 kilometers. Now above the troposphere is the stratosphere. In the stratosphere we find gases like ozone. The stratosphere is very diffuse, not very dense. And yet somehow what happens in this diffuse layer up in the stratosphere affects the climate that we feel at the surface. We don't really understand very well the mechanisms, the processes that cause this diffuse layer high up to affect the weather down at the ground. So that's very much the focus of my work. Google is going to be flying balloons in the stratosphere to provide internet connectivity for people during natural disasters. This provides science with a unique opportunity to get a lot more data than we've ever been able to get in the past to understand stratospheric dynamics. Because these balloons will float in the stratosphere and will, as has been the case with previous balloon campaigns, trace the motion of air in the stratosphere. Looking at the way air moves in the stratosphere we hope to better understand the processes that control the fingerprint of various gases on the climate system because it's that control from the stratosphere that we're really looking to understand.
