This Town Hall will update the community on opportunities for Tropical Pacific field campaigns to support the Tropical Pacific Observing System (TPOS), and advance the goals of NOAA’s Precipitation Prediction Grand Challenge and the WCRP Global Precipitation Experiment. We will discuss upcoming process studies in the Tropical Pacific, TPOS implementation, and their key roles in supporting national and international initiatives. This is an opportunity to share NOAA program science plans with the broader science community, encourage community and other agency engagement, and enhance national and international collaborations. NOAA’s programs invite collaborations with the science community, other agencies, and international partners. NOAA Climate Variability and Predictability Program supports research for process studies: Pacific Upwelling and Mixing Physics and Air–sea Interaction at the eastern edge of the Warm Pool (TPOS 2020 Reports). It is anticipated that NOAA, and national and international partners will pursue a process study field effort in the Tropical Pacific in 2026 or 2027. NOAA Global Ocean Monitoring and Observing Program, with national and international partners, supports TPOS and advancement of the TPOS 2020 Project recommendations. We will discuss TPOS implementation status and upcoming process studies and provide an opportunity for community feedback, collaboration, and innovation.
