Mission Science Objectives

PACE's core objectives, questions, and applications dictated mission requirements that shaped the Ocean Color Instrument design and inclusion of the SPEXone and HARP2 polarimeters. The mission science objectives below evolved from the work of the PACE Science Definition Team.

PACE in orbit
Extend key systematic ocean biological, ecological, and biogeochemical climate data records and cloud and aerosol climate records.
Earth biosphere
Make new global measurements of ocean color to improve our understanding of the carbon cycle and ocean ecosystem responses to a changing climate.
Earth atmosphere
Collect global observations of aerosol and cloud properties, focusing on reducing the largest uncertainties in climate and radiative forcing models of the Earth system.
Improve our understanding of how aerosols influence ocean biogeochemical cycles and ecosystems and how ocean biological and photochemical processes affect the atmosphere.
