active Mission
Artist's concept of PACE spacecraft

PACE will help us better understand our ocean and atmosphere by measuring key variables associated with cloud formation, particles and pollutants in the air, and microscopic, floating marine life (phytoplankton). These observations will help us better monitor ocean health, air quality, and climate change.
