Atmosphere Observing System (AOS)


Flight Project


Under Study



NASA's new Earth System Observatory (ESO) will provide key information related to climate change, natural hazard mitigation, fighting forest fires, and improving real-time agricultural processes.

The Atmosphere Observing System (AOS) will address two of the five ESO areas of focus including:

- Aerosols: Answering the critical question of how aerosols determine air quality and affect the global energy balance, a key source of uncertainty in predicting climate change.

- Cloud, Convection, and Precipitation: Tackling one of the largest sources of uncertainty in future projections of climate change and targeting processes that influence the prediction of severe weather.
