NCEI is currently moving its data and applications to the cloud. This upgrade may result in temporary data access delays. Please see our cloud migration overview and frequently asked questions for more information and resources. Check the NCEI Alerts page for impacted products and datasets. Current Impact: Intermittent degraded order fulfillment services.
NCEI, the National Centers for Environmental Prediction (NCEP), and the Geophysical Fluid Dynamics Laboratory provide remote access to high-volume numerical weather prediction and global climate models and data. These organizations share a repository that includes weather model output datasets, model input datasets (assimilation), and a limited subset of NOAA climate model datasets.
NCEI provides near-real-time access to the forecast data these models generate, in addition to historical model data. The model data repository also services derived/other model data including paleoclimate (tree ring and ice core) data, observational, and derived observational datasets to promote interoperable, multi-disciplinary data analysis.
