Our atmosphere consists of several layers and each plays a different role in our climate. The bottom two layers are the troposphere and the stratosphere, and in between these two is a region of colder air known as the Tropopause. It is critical to understand the Tropopause, its composition and interaction with gases, aerosols, and humidity that affect the stratosphere's climate, which ultimately affects the climate in the troposphere. NASA launched a mission called Airborne Tropical TRopopause Experiment (ATTREX) to find answers to these questions.

This 9-minute, 30-second video describes how our atmosphere consists of several layers and how each plays a different role in our climate. The bottom two layers are the troposphere and the stratosphere, and in between these two is a region of colder air known as the Tropopause. It is critical to understand the Tropopause, its composition and interaction with gases, aerosols, and humidity that affect the stratosphere's climate, which ultimately affects the climate in the troposphere. NASA launched a mission called Airborne Tropical TRopopause Experiment (ATTREX) to find answers to these questions. Operated by NASA's Armstrong Flight Research Center, the remotely piloted Global Hawk research aircraft took off from its base at Edwards, CA, to track the transport of water vapor into the upper atmosphere and help researchers understand how greenhouse gases affect Earth's climate.

This 10-minute, 46-second video shows how our atmosphere consists of several layers and each plays a different role in our climate. The bottom two layers are the troposphere and the stratosphere, and in between these two is a region of colder air known as the Tropopause. It is critical to understand the Tropopause, its composition and interaction with gases, aerosols, and humidity that affect the stratosphere's climate, which ultimately affects the climate in the troposphere.

The water cycle and its role in ATTREX. Our atmosphere consists of several layers and each plays a different role in our climate. The bottom two layers are the troposphere and the stratosphere, and in between these two is a region of colder air known as the Tropopause. It is critical to understand the Tropopause, its composition and interaction with gases, aerosols, and humidity that affect the stratosphere's climate, which ultimately affects the climate in the troposphere.

This 12-minute, 15-second video shows the January 2014 Airborne Tropical TRopopause Experiment (ATTREX). Our atmosphere consists of several layers and each plays a different role in our climate. The bottom two layers are the troposphere and the stratosphere, and in between these two is a region of colder air known as the Tropopause. It is critical to understand the Tropopause, its composition and interaction with gases, aerosols, and humidity that affect the stratosphere's climate, which ultimately affects the climate in the troposphere. NASA launched the ATTREX mission to find answers to these questions. NASA's unmanned aerial vehicle (UAV) Global Hawk tracked changes in the upper atmosphere to help researchers understand how these changes affect Earth's climate. The Global Hawk is operated by the Armstrong Flight Research Center, Edwards, CA.
