Earth's Atmospheric Layers
International Space Station astronauts captured this photo of Earth's
atmospheric layers on July 31, 2011, revealing the troposphere (orange-red),
stratosphere and above. Satellite instruments allow scientists to better
understand the chemistry and dynamics occurring within and between these
layers.
NASA monitors Earth’s vital signs from land, air and space with a fleet of
satellites and ambitious and ground-based observation campaigns. NASA develops
new ways to observe and study Earth’s interconnected natural systems with
long-term data records and computer analysis tools to better see how our planet
is changing. The agency shares this unique knowledge with the global community
and works with institutions in the United States and around the world that
contribute to understanding and protecting our home planet.
