Please note: Due to a system outage, many NCEI systems are currently unavailable. We apologize for any inconvenience.
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.
