> DATA PRODUCT DESCRIPTIONGo to Dataset: In addition to the products described below, selected reanalysis output
fields are also put on cdroms. The detailed information about Reanalysis
cdroms can be found at Reanalysis CDROMs.
More than 20 different data products are output from the Reanalysis
data assimilation, model run, and model forecast. These products are
defined in terms of the NCAR archive names, physical variables,
resolutions (temporal and spatial), and media storage size.
A summary
of variables in NCEP/NCAR Reanalysis archive is available in addition to
the detailed list of all varibales.
The reanalysis datasets stored at NCAR are:
- ds090.0,
NCEP Global Reanalysis, Anals, 6-hrly
- ds090.1,
NCEP Global Reanalysis, 8-Day Forecast, every 5 Days
- ds090.2,
NCEP Reanalysis Monthly Data Subsets (from DS090.0)
- Selected Monthly Means
extracted from ds090.0, free by ftp
In general, the reanalysis archive has the following categories:
- Data Format -
- GRIB- Most of the data is in GRIB format,
doc,
decoder
- BUFR- Observations are in BUFR format,
doc,
decoder
- Cray Binary Format- including
sanl, sges, sfcanl, bges, znl.f00, znl.f06 file_types
- Data File_Types
- Analysis-In our
ds090.0 dataset
- 6-hour Forecast-In our
