Dataset
ECMWF ERA-40: reduced N80 Gaussian gridded model level forecast data (ggfm)
Abstract
ERA-40 was a European Centre for Medium-Range Weather Forecasts (ECMWF) global atmospheric reanalysis project covering the period September 1957 to August 2002. This follows on from the ERA-15 re-analysis project. The dataset includes data on surface, PV, potential temperature and pressure surfaces. Model level data available as GRIB formatted data on spectral and reduced Gaussian grids. Access limited to UK based academic researchers only
