Global precipitation observations are vital for investigating processes that impact extreme weather, hydrologic forecasts, and infrastructure. The TRMM and GPM missions have set  standards for global precipitation remote sensing and applications, and future international agency and commercial missions will further advance our observational record and understanding of physical processes. Emerging concerns in space-based global precipitation observations include an increasing reliance on high-frequency microwave channels and the improved temporal sampling enabled by smallsats in an evolving precipitation constellation.  Advancing precipitation science and applications requires understanding these concerns, utilizing complementary cloud-precipitation observations from spaceborne and suborbital platforms, and embracing model-observation synergy to document detailed interaction processes across fine spatial and temporal scales. This session invites innovative contributions in precipitation science and applications with an emphasis on the use of space-based observations, including missions, instrumentation, algorithms, quantitative precipitation estimation, uncertainty characterization, and validation, and extending to interdisciplinary research on extremes, processes, and models.
