The South America Affinity Group (SAAG) was established in early 2019 by the NationalCenter for Atmospheric Research (NCAR) Water Systems Program as a community effortfocused on improving hydroclimate science over South America. SAAG supports large researchefforts such as the ANDEX Regional Hydroclimate Program (Espinoza et al. 2020) as well asindividual research groups. The group started with a dozen members and quickly grew to over100 participants from more than ten countries. For the past four years, the SAAG has beenmeeting online every two weeks and has organized sessions at international conferences such asthe American Geophysical Union Fall Meeting and the Convection-Permitting ClimateWorkshop (Prein et al. 2022). At the core of the SAAG effort are two multi-decadal convection permitting(CP) model simulations with 4-km grid spacing for historical and future climates overthe South American continent. Additionally, a major observational data collection effort has beenundertaken, including in-situ station data from South American meteorological and waterservices, gridded products, satellite-based observations, and field campaign data (NCAR, 2023a).This article discusses the research needs and scientific goals that drive this community ofscientists with diverse backgrounds and interests.
