Description:
The monthly means of NCEP/NCAR Reanalysis (R1) products,
archived in ds090.0 dataset,
are extracted and reorganized into subgroups in this dataset. The groupings try to combine like and/or commonly used parameter-level data together. There are also subgroups for each of the four diurnal monthly means (means of 00Z, 06Z, 12Z, and 18Z separately).
The data files are in WMO GRIB format. Both the monthly means
and their variances are in the same file but in different GRIB

Description:
The Final (FNL) global tropospheric analyses archived here were produced by NCEP's Global Forecast System (GFS), which was run operationally at 12-hour intervals to make multiple-day weather forecasts, from July 1976 through mid-April 1997. FNLs are analyses that are produced after the model has completed the forecast cycle, and they include the most complete set of observations available for a given cycle. The FNL from a given cycle, which is the best available analysis, is then used in…

Description:
Important Notice: Update of JRA-55 data will terminate at the end of January 2024. Please use Japanese Reanalysis for Three Quarters of a Century (JRA-3Q) at that time.
The Japan Meteorological Agency (JMA) conducted JRA-55, the second Japanese global atmospheric reanalysis project. It covers 55 years, extending back to 1958, coinciding with the establishment of the global radiosonde observing system. Compared to its predecessor, JRA-25, JRA-55 is based on a new data assimilation and p…

Description:
For RDA ERA5 monthly mean data prior to 1979, please see ds633.5:
ERA5 monthly mean back extension 1950-1978 (Preliminary version)
After many years of research and technical preparation, the production of a new ECMWF climate reanalysis to replace ERA-Interim is in progress. ERA5 is the fifth generation of ECMWF atmospheric reanalyses of the global climate, which started with the FGGE reanalyses produced in the 1980s, followed by ERA-15, ERA-40 and most recently ERA-Interim. ERA5 w…

Description:
The Japan Meteorological Agency (JMA) conducted JRA-55, the second Japanese global atmospheric reanalysis project. It covers 55 years, extending back to 1958, coinciding with the establishment of the global radiosonde observing system. Compared to its predecessor, JRA-25, JRA-55 is based on a new data assimilation and prediction system (DA) that improves many deficiencies found in the first Japanese reanalysis. These improvements have come about by implementing higher spatial resolution (TL319L…

The monthly means of surface and flux fields from ECMWF ERA-40 reanalysis project are in this dataset.

For ancillary use only - not recommended as a primary research dataset. It has likely been superseded by newer and better datasets.
Description:
The 6-hourly global upper air model level analysis data from ECMWF ERA-40 reanalysis project are in this dataset.

For ancillary use only - not recommended as a primary research dataset. It has likely been superseded by newer and better datasets.
Description:
ERA-Interim represents a major undertaking by ECMWF (European Centre for
Medium-Range Weather Forecasts) to produce a reanalysis with an improved
atmospheric model and assimilation system which replaces those used in ERA-40,
particularly for the data-rich 1990s and 2000s, and to be continued as an
ECMWF Climate Data Assimilation System (ECDAS) until superseded by a new
extended reanalysis. Preliminary runs indicated that several of the
inaccuracies exhibited by ERA-40 su…

Description:
The 6-hourly global upper air pressure level analysis data from ECMWF ERA-40 project are in this dataset.

For ancillary use only - not recommended as a primary research dataset. It has likely been superseded by newer and better datasets.
Description:
DS126.0 represents a dataset implemented and computed by NCAR's Data Support Section, and forms an essential
part of efforts undertaken in late 2004, early 2005, to produce an archive of selected segments of ERA-40 on a
standard transformation grid.
In this case, forty seven ERA-40 monthly mean surface and single level analysis
variables were transformed from a reduced N80 Gaussian grid to a 256 by 128 regular Gaussian grid. All fields were
transformed using routines fr…
