Building on the original AIFS introduced in 2024, AIFS 2.0 demonstrates a 40% improvement in medium-range (7–15 day) forecast accuracy, particularly for extreme weather events such as cyclones and atmospheric rivers. The system integrates real-time data from over 100 satellite sources and uses a transformer-based neural network trained on 50 years of ERA6 reanalysis data.  \n   *Source: ECMWF, https://www.ecmwf.int/en/newsletter/178/news/ecmwf-launches-ai-powered-aifs-20 (March 2026)*\n\n2. **NOAA’s Unified Forecast System (UFS) v2.5 with Sub-Kilometer Resolution**  \n   The U.S. National Oceanic and Atmospheric Administration (NOAA) released version 2.5 of its Unified Forecast System, now capable of running 1-km resolution deterministic forecasts over North America for up to 7 days. This resolution allows for explicit simulation of convective storms without relying on parameterization. The model is operational on NOAA’s new \"Orion\" supercomputer, which delivers 40 petaflops dedicated to weather modeling.  \n   *Source: NOAA, https://www.noaa.gov/ufs-v2-5-release (February 2026)*\n\n3. **NASA and JAXA Joint Release of GPM-Next Satellite Data**  \n   The Global Precipitation Measurement Follow-On (GPM-Next), a joint mission by NASA and the Japan Aerospace Exploration Agency (JAXA), began transmitting high-resolution 3D precipitation data","keywords":["ocean-earth-science","neural-networks","climate-change","zo-research"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"},"dateCreated":"2026-04-11T14:23:18.098823Z","dateModified":"2026-05-09T02:03:18.054364Z","additionalProperty":[{"@type":"PropertyValue","name":"trust_level","value":45},{"@type":"PropertyValue","name":"verification_status","value":"unverified"},{"@type":"PropertyValue","name":"provenance_status","value":"valid"},{"@type":"PropertyValue","name":"evidence_level","value":"institutional"},{"@type":"PropertyValue","name":"content_hash","value":"7eb1d3e84a65e54f5934246d49ed059b36ad5f136e93d22216b660ff4d7224bd"}]}
