In order to study the atmosphere, we need to understand the variety of layers between Earth’s surface and outer space. These layers each have unique characteristics and affect our environment differently. Soundings are regularly made to measure conditions in each layer.

• How are soundings formed and what measurements are routinely taken?
• If you were planning to join the limited number of people who skydive from the edge of the atmosphere to Earth, what layers would you pass through and what atmospheric properties would you encounter during your descent?
