ECMWF AIFS Single - dynamical.org Icechunk Zarr

The Artificial Intelligence Forecasting System (AIFS) is a data driven forecast model developed by the European Centre for Medium-Range Weather Forecasts (ECMWF). This is the non-ensemble configuration of AIFS that produces a single forecast trace. AIFS is trained on ECMWF's ERA5 re-analysis and ECMWF's operational numerical weather prediction (NWP) analyses. These datasets have been translated to cloud-optimized Icechunk Zarr format by [dynamical.org](https://dynamical.org). - [ECMWF AIFS Singl
