Study Finds Asian Monsoon Carries Pollution Into the Stratosphere

Green Car Congress

Scientists have long known that air over the tropics moves upward between the lower atmosphere and the stratosphere, part of a large-scale pattern known as the Brewer-Dobson circulation. This could explain satellite measurements showing high levels of stratospheric ozone, water vapor and other chemicals over Asia during summer.
