NCAR (Boulder, CO, USA) gets the complete Reanalysis Output. Outside users can obtain tapes for a fee. They are equipped to handle data distribution and are able to answer some questions. Some datasets are freely available over the internet.

ESRL/PSD, the center once known as CDC, (Boulder CO, USA) also receives the complete Reanalysis Output. The have been providing outside users with NetCDF data on DLT tapes. They have been very active in screening the data and providing feedback. In addition, they have a large subset of the data online, have software to read NetCDF and are able to answer some questions.

NCDC (Ashville, NC, USA) is the official US government archive for climate information and have a copy of NCEP Reanalyses. The NOMADS site at NCDC has some reanalysis data.
