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 synoptic monthly mean accumulated forecast surface level data on a reduced N256 Gaussian grid. Forecast steps are every 3 hours from the 00 and 12 UT analysis times.

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.
