Abstract:
The NCEP North American Regional Reanalysis products are on the Eta 221 grid
at 29 pressure levels. They were produced using the Eta 32 km model with 45 vertical layers.
The input data includes all observations used in NCEP/NCAR Global Reanalysis
project, and additional precipitation data, TOVS 1B radiances, profiler data,
land surface and moisture data, etc. The output analyses are 3-hourly with
additional 9 variables in the 3-hour forecasts to reflect accumulations or
averages.
NARR reruns from 20090311 to 20091214 are updated on February 4, 2010. In April 2015, NCEP has released rerun 4 from April 1, 2009 to January 31, 2015 to fix codes and Mexico precipitation data preparation.

Metadata Record:
Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the https://makedatacount.org/ project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
