The Plankton, Aerosol, Cloud, and Ocean Ecosystem (PACE) mission is NASA’s next great investment in Earth Science, continuing NASA’s legacy of over forty years of satellite ocean color measurements. PACE, expected to launch in 2023, will advance our Earth-observing and monitoring capabilities through hyperspectral imaging and multi-angle polarimetric observations of ocean, atmosphere, and land ecosystems. PACE will give us an unprecedented view of our home planet and will support user-driven environmental applications through research and applied science to address societal challenges and inform decision-making. The PACE Applications program seeks to strengthen the ties between science and decision-making through programming such as the Early Adopter initiative, workshops and focus sessions, and information-sharing and co-production activities. Practical applications of PACE data include waterborne pathogen monitoring and prediction, harmful algal bloom species discrimination and early-detection, support for best-management practices for estuary and watershed health, as well as sustainable fishery and aquaculture practices. Hyperspectral and polarimetric PACE data will provide water resource managers and decision-makers with highly accurate ocean color and atmospheric observations that will directly improve their operational products and applied technologies, ultimately fulfilling real-world needs. This presentation will highlight PACE’s novel hyperspectral and polarimetric capabilities, introduce PACE’s standard and exploratory data products, outline the PACE Applications Program, share real-world coastal applications of PACE data, and summarize the results of the 2021 PACE Applications Water Quality Focus Session and the 2021 PACE Applications Workshop as they relate to community engagement and capacity development. Finally, we will share the revamped PACE Applications Outreach Strategy and how it will be used to promote partnerships within the existing user communities of practice and new user communities of potential for greater societal benefit.
