ECMWF ERA-Interim: reduced N256 Gaussian gridded model level accumulated forecast parameters data (gafm)
Abstract
Accumulated forecast parameters on a reduced N256 Gaussian grid from the European Centre for Medium-Range Weather Forecasts (ECWMF) ERA-Interim programme.
The ERA-Interim global atmospheric reanalysis of the covers 1979 to August 2019. This follows on from the ERA-15 and ERA-40 re-analysis projects.
This subset of the ERA-Interim dataset contains 14 parameters on 60 model levels covering clear sky long and short wave radiation, up- and down-draft parameters, total precipitation, temperature and humidity tendencies, turbulent diffusion coefficient for heat, zonal and meridional wind tendencies.

Process overview
Title | ECMWF ERA-Interim Re-analysis Model deployed on ECMWF Computer |
Abstract | This computation involved: ECMWF ERA-Interim Re-analysis Model deployed on ECMWF Computer. The data assimilation system used to produce ERA-Interim is based on a 2006 release of the IFS (Cy31r2). The system includes a 4-dimensional variational analysis (4D-Var) with a 12-hour analysis window. The spatial resolution of the data set is approximately 80 km (T255 spectral) on 60 vertical levels from the surface up to 0.1 hPa. |
