Projekt reanalizy NCEP/NCAR to wspólne przedsięwzięcie National Centers for Environmental Prediction (NCEP, dawniej „NMC”) i National Center for Atmospheric Research (NCAR). Celem tego wspólnego przedsięwzięcia jest opracowanie nowych analiz atmosferycznych na podstawie danych historycznych, a także analiz stanu atmosfery w czasie rzeczywistym (Climate Data Assimilation System, CDAS). W projekcie NCEP/NCAR Reanalysis 1 wykorzystywany jest najnowocześniejszy system analizy i prognozowania do asymilacji danych z okresu od 1948 r. do dziś. Dane mają rozdzielczość czasową 6 godzin (0000, 0600, 1200 i 1800 UTC) oraz rozdzielczość przestrzenną 2, 5 stopnia.

The NCEP/NCAR Reanalysis 1 project is using a\nstate-of-the-art analysis/forecast system to perform data assimilation using\npast data from 1948 to the present. The data have 6-hour temporal\nresolution (0000, 0600, 1200, and 1800 UTC) and 2.5 degree spatial\nresolution.\n\nBands\n\n\n**Pixel Size**\n\n278300 meters\n\n**Bands**\n\n| Name | Units | Min | Max | Pixel Size | Description |\n|-------|-------|---------|---------|------------|-------------------------|\n| `air` | K | 187.3\\* | 323.5\\* | meters | Surface air temperature |\n\n\\* estimated min or max value\n\nTerms of Use\n\n**Terms of Use**\n\nThere are no restrictions on the use of these datasets.\n\nCitations \nCitations:\n\n- Kalnay et al., 1996, The NCEP/NCAR 40-Year Reanalysis Project.
