PARDIG

Google DeepMind has publicly released SatWeave and PARDIG, the two foundational datasets behind its WeatherNext 3 weather model, both hosted on Google Cloud Storage under CC BY 4.0. PARDIG uses a spherical-grid Transformer with ~10 km spatial and 15-minute temporal resolution, outperforming NASA IMERG-Final by over 30% on hourly light-to-moderate precipitation detection and remaining reliable in regions lacking ground radar.

Google DeepMind's WeatherNext team released SatWeave and PARDIG, two foundational datasets for building weather, hydrology, and climate applications. Both underpin the recently launched WeatherNext 3 model, and their open release lowers the data barrier for researchers worldwide.
