The Pre-Aerosol, Clouds, and ocean Ecosystem (PACE) mission will make global ocean color measurements essential for understanding the carbon cycle and how it both affects and is affected by climate change, along with polarimetry measurements to provide extended data records on clouds and aerosols. New and continuing global observations of ocean ecology, biology, and chemistry are required to quantify aquatic carbon storage and ecosystem function in response to human activities and natural events. The PACE mission will serve to make these measurements until the readiness of the more advanced Aerosol, Cloud, and Ecosystems (ACE) mission recommended by the National Academies Decadal Survey for its Tier 2 mission set.
