ECMWF ERA-Interim: reduced N256 Gaussian gridded synoptic monthly mean forecast pressure level parameter data (hgfp)

ERA-Interim is the latest European Centre for Medium-Range Weather Forecasts (ECMWF) global atmospheric reanalysis of the period 1979 to August 2019. This follows on from the ERA-15 and ERA-40 re-analysis projects. The dataset includes synoptic monthly mean forecast pressure level data on a reduced N256 Gaussian grid. Forecast steps are every 3 hours from the 00 and 12 UT analysis times.
