What if swapping your weather model was boring? How dynamical.org is making AI weather forecasting accessible on AWS

This article describes how dynamical.org is making AI weather forecasting accessible on AWS through standardized, cloud-optimized datasets.

• dynamical.org hosts major operational weather models in unified Icechunk 2.0 Zarr format on S3
• Catalog includes NOAA GFS, GEFS, HRRR, ECMWF IFS ENS, NOAA MRMS, and ECMWF AIFS AI model
• Normalizes metadata, variable names, and access patterns across different modeling centers
• ECMWF AIFS produces global forecasts in minutes on single GPU versus hours on supercomputers
• Simple Python API enables swapping between physics-based and AI weather models with one line
• Available through Registry of Open Data on AWS with example notebooks and tutorials

dynamical.org eliminates integration complexity for weather data, enabling researchers and developers to easily experiment with and compare traditional and AI-based forecasting models.
