Abstract:
This dataset contains products from the NCEP/DOE
Reanalysis 2 (R2) Project. The resolution of the
R2 model is the same as NCEP/NCAR Reanalysis (R1) project,
T62 Gaussian grids with 28 vertical sigma levels. The output fields
are saved 4 times a day as in R1. The main objective of the R2
project is to correct known errors in the R1 project and update
the parameterizations of the physical processes.
Improvements are seen in surface flux fields, hydrological budget,
short wave radiation flux, etc. There are also drawbacks found
in the outgoing longwave radiation over tropical warm pool and
upper-level tropical moisture. R2 plans to reanalyze the data
starting from 1979 and going forward only.
The main R2 products archived at NCAR consitute of 6 subgroups:
pressure level analysis, sigma level analysis, flux term analysis, diagnostic analysis
and 6-hour forecasts of flux term and
diagnostic terms. All data files are in GRIB format
and archived by month.
This dataset is updated once a month. Limited amount of recent data
are also available at NCEP (https://ftp.cpc.ncep.noaa.gov/wd51we/reanalysis-2/).
Earth System Research Laboratory's Physical Sciences Division of NOAA has the same data in
netCDF format at https://www.esrl.noaa.gov/psd/data/gridded/data.ncep.reanalysis2.html.

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.
