Earth's upper atmosphere is an open system that is strongly influenced by energy and momentum inputs from both above and below. New observation and modeing techniques have provided insights into dynamics, energetics, and chemical processes in the upper atmosphere.
Upper Atmosphere Dynamics and Energetics presents an overview of key research advances in upper atmospheric physics, and measurement and modeling techniques, along with remaining challenges for understanding the state and variability of the upper atmospheric system.
Volume highlights include:
- Insights into the interconnections between different areas of upper atmospheric science - Appreciation of the dynamics and complexity of the global upper atmospheric system - Techniques for observing and measuring the upper atmosphere - Responses of the upper atmosphere to external drivers
The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.
