PACE will help us pinpoint ocean-atmosphere connections that affect our everyday lives. For example, it will reveal how particles suspended in our atmosphere, known as aerosols, impact the growth of phytoplankton, tiny algae suspended in our ocean. Phytoplankton provide the oxygen we breathe and help reduce carbon dioxide levels in our atmosphere.

PACE extends and expands NASA's observations of our living planet, pioneering new ways to take Earth's pulse for decades to come.
