任务简介

PACE（浮游生物、气溶胶、云、海洋生态系统）是NASA的一项地球观测卫星任务。它将进行全球海洋颜色测量，以提供关于海洋生态和全球生物地球化学（如碳循环）的扩展数据记录，同时进行偏振测量，以提供关于云和气溶胶的扩展数据记录。

PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) is a NASA Earth observation satellite mission. It will make global ocean color measurements to provide extended data records on ocean ecology and global biogeochemistry (e.g., carbon cycle) along with polarimetry measurements to provide extended data records on clouds and aerosols.
