ERA-40 2.5° by 2.5° reanalysis archive containing primary (4-times daily GRIB) and processed (4-times daily and climatological netCDF)data. The atmospheric model used for ERA-40 has the identifier IFS CY23r4 and is comprehensively documented on the ECMWF website at http://www.ecmwf.int/research/ifsdocs/CY23r4/index.html. It has 60 levels in the vertical, uses a T159 spherical-harmonic representation for the dynamical fields, and a reduced Gaussian grid with an approximately uniform 125 kilometre spacing for surface and other grid-point fields. An essential part of the ERA-40 activity was the production of an archive of data in GRIB format. Parameters such as the 4-times daily surface and pressure level files were processed to produce COARDS conforming netCDF files which are self describing, machine transperant and which employ a similar metacode specification to that in the NCEP re-analysis files. This makes it possible for users of the NCEP/NCAR reanalysis to be able to easily switch data input to ERA-40. Only the 4-times daily GRIB files have been further processed and are on a 2.5 by 2.5 degree horizontal grid (144 by 73 regular grid points) for each of the standard 23 pressure levels (0001, 0002, 0003, 0005, 0007, 0010, 0020, 0030, 0050, 0070, ...
