ERA5 1979 onward becoming available in the RDA

CISL DECS is processing ERA5, 1979 onward, into netCDF4/HDF5 files containing single parameter 0.25° gridded time series. Please refer to ds633.0,

ERA5 Reanalysis (0.25 Degree Latitude-Longitude Grid)

for further information and availability.

Please note: DECS is producing a CF 1.6 compliant netCDF-4/HDF5 version of ERA5 for the CISL RDA at NCAR. The netCDF-4/HDF5 version is the de facto RDA ERA5 online data format. The GRIB1 data format is only available via NCAR's High Performance Storage System (HPSS). There is a one-to-one correspondence between the netCDF-4/HDF5 and GRIB1 files, with as much GRIB1 metadata as possible incorporated into the attributes of the netCDF-4/HDF5 counterpart.
