They generated training data from existing chemistry-climate simulations and trained CorrDiff on the Isambard-AI supercomputer using a year of hourly UK pollution data, producing a UK-wide model at 2-3 square km resolution. Training took two days on a single eight-GPU node, and the workflow also runs on an NVIDIA DGX Spark desktop system for inference and smaller training runs.","company":"University of Manchester","industry":"Education","country":"United Kingdom","aiCapabilities":["Generative AI","Predictive Analytics"],"technology":["NVIDIA Earth-2"],"deployment":"Unknown","problemStatement":"Computing air quality with traditional chemistry-based models is expensive, which limits how detailed they can be and how regularly they can be run.","solutionApproach":"The team generated training data from existing chemistry-climate simulations, then trained NVIDIA Earth-2 CorrDiff, a generative downscaling model, on the Isambard-AI supercomputer, and has since added Earth-2 StormCast for time-dependent forecasts that use air quality observations.","businessValue":"Training the UK-wide pollution model took two days on a single eight-GPU node, and the same workflow runs on an NVIDIA DGX Spark desktop system for inference and smaller training runs. Applications such as proactive air quality alerts for healthcare organisations are described as envisioned.","evidence":{"band":"high"},"sourceUrl":"https://blogs.nvidia.com/blog/uk-air-pollution-research-earth-2/","dates":{"publishedAt":"2026-10-14T05:45:47.792Z","publishedAtSource":"pipeline","updatedAt":"2026-10-14T05:45:47.792Z"},"license":"Open for reading and citing with a link to https://findausecase.com/use-cases/university-of-manchester-uses-nvidia-earth-2-to-forecast-air-pollution-across-the-uk.
