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.
