Background 

The Global Precipitation EXperiment (GPEX) is a WCRP Lighthouse Activity aiming to accelerate advances in observing, understanding, and predicting precipitation, including extremes, across regions and seasons. It integrates coordinated field campaigns, open/FAIR data development, modeling-to-application pathways, and regional/national activities with capacity development through four Working Groups (WGs): 

  • WG1 – Coordinated Field Campaigns (e.g., AR Recon) 
  • WG2 – Data Development (archives, access, QC/validation, FAIR, integration) 
  • WG3 – Prediction & Modeling (forecasting, km-scale ensembles, model evaluation) 
  • WG4 – Regional/National Activities & Capacity Development (engaging scientists, training, EMCR networks, visualization products, regional liaisons) 

Purpose & Objectives 

The GPEX Multistakeholder Workshop will: 

  • Showcase early findings and advances from the four GPEX Working Groups (field campaigns, data development, prediction and modeling, and regional/national activities with capacity development). 
  • Engage with regional and international partners – research institutions, space agencies, national meteorological and hydrological services, and operational centers focused on observations and modeling. 
  • Initiate collaborations across science, applications, and services to accelerate advances in precipitation research. 
  • Bring together planned and future field campaigns on precipitation drivers (atmospheric rivers, monsoons, mesoscale convective systems, tropical cyclones), creating synergies across regions and disciplines. 
  • Advance the vision of the WCRP “Years of Precipitation (YoP)” as a unifying framework for coordinated global field campaigns, enhanced data development, prediction experiments, and capacity development.
