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.

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.
