The Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission, launched February 8 th, 2024, is part of the Program of Record of the National Academies of Sciences, Engineering and Medicine (NASEM) report Thriving on Our Changing Planet: A Decadal Strategy for Earth Observations from Space. PACE’s primary instrument, the Ocean Color Instrument (OCI), spans from the ultraviolet to near-infrared spectral regions, with an additional seven discrete shortwave infrared bands. This instrument is complemented by two small, multi-angle polarimeters with spectral ranges that span the visible to near-infrared region. Thus, the mission performs radiometric and polarimetric ocean and atmosphere surveys, returning a range of geophysical data from which properties of the ocean and atmosphere can be produced to add to other critical climate and Earth system variables. The capabilities of the OCI not only extend atmospheric and ocean data records from the EOS-era instruments, but PACE also observes the terrestrial biosphere and cryosphere, providing additional measurements of the Earth system at unprecedented hyperspectral resolution. PACE represents a critical climate continuity mission.

This ROSES element requests proposals that focus on innovative uses of PACE data to answer integrated disciplinary or inter-disciplinary Earth system science research and applied questions. These investigations must focus on pursuing research within and/or across the Earth System (atmospheric, cryospheric, terrestrial, and aquatic environments), quantifying change, characterizing processes, and improving the understanding of the functioning of the Earth System’s components and the interactions among them.
