ECMWF ERA-Interim: reduced N256 Gaussian gridded surface level accumulated forecast parameters data (ggfs)
Abstract
Surface level 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 34 parameters covering boundary layer, precipitation, radiation, wind, evaporation, run-off, gravity wave and surface heat flux data.
The 34 parameters are: Clear sky surface photosynthetically active radiation; Downward UV radiation at the surface; Photosynthetically active radiation at the surface; Evaporation; TOA incident solar radiation; Stratiform precipitation (Large-scale precipitation); Convective precipitation; Snowfall (convective + stratiform); Boundary layer dissipation; Surface sensible heat flux; Surface latent heat flux; Surface solar radiation downwards; Surface thermal radiation downwards; Surface solar radiation; Surface thermal radiation; Top solar radiation; Top thermal radiation; East-west surface stress; North-south surface stress; Sunshine duration; Latitudinal component of gravity wave stress; Meridional component of gravity wave stress; Gravity wave dissipation; Runoff; Total precipitation; Convective snowfall; Large-scale snowfall; Large-scale precipitation fraction; Top net solar radiation, clear sky; Top upward thermal radiation, clear sky; Surface net solar radiation, clear sky; Surface net thermal radiation, clear sky; Snow evaporation; and, Snowmelt.

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. |
