The NCEP/NCAR Reanalysis is an atmospheric reanalysis produced by the National Centers for Environmental Prediction (NCEP) and the National Center for Atmospheric Research (NCAR). It is a continually updated globally gridded data set that represents the state of the Earth's atmosphere , incorporating observations and numerical weather ...

The archive is maintained by the Data Support Section of the Computational and Information Systems Laboratory] (CISL) at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado. The archive acquires, curates, preserves and disseminates an extensive list of over 700 data sets. Registration is free and open to the general public.
To address a growing need for remote access to high volume numerical weather prediction and global climate models and data, the National Climatic Data Center (NCDC), along with the National Centers for Environmental Prediction (NCEP) and the Geophysical Fluid Dynamics Laboratory (GFDL), initiated the NOAA Operational Model Archive and Distribution System (NOMADS) project.
National Hurricane Center provides forecasts of the movement and strength of tropical weather systems and issues watches and warnings for the North Atlantic and the Eastern Pacific Ocean. NCEP Central Operations sustains and executes the operational suite of numerical analyses and forecast models and prepares NCEP products for dissemination.
Although data can be subject to accuracy issues due to the extrapolation techniques used, the usage of modeled data is a commonly accepted practice in climate and meteorological sciences. Oftentimes, these models will be used in concert with in-situ measurements. A few well-known models are NCEP/NCAR Reanalysis Project, an atmospheric model [4]
NCAR is managed by the nonprofit UCAR and is one of the NSF's Federally Funded Research and Development Centers, with approximately 95% of its funding coming from the federal government. However, it is not a federal agency and its employees are not part of the federal personnel system. [3] NCAR employs about 761 staff.
The Advanced Research WRF (ARW) is supported to the community by the NCAR Mesoscale and Microscale Meteorology Laboratory. [6] The WRF-NMM solver variant was based on the Eta model, and later nonhydrostatic mesoscale model, developed at NCEP. The WRF-NMM (NMM) is supported to the community by the Developmental Testbed Center (DTC).
