Dataset
ECMWF ERA-Interim: reduced N256 Gaussian gridded monthly mean of daily mean forecast pressure level parameter data (ggfp)
Abstract
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 monthly mean of daily mean forecast pressure level data on a reduced N256 Gaussian grid.

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. |
