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

This dataset contains daily monthly average, N80 Gaussian gridded, model level, analysis timestep parameters from the European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA) 40 program from August 1958 to September 2002. ERA-40 followed on from the ERA-15 re-analysis project. Access limited to UK based academic researchers only. These data are GRIB formatted.

This dataset contains 6-hourly monthly average, N80 Gaussian gridded, potential temperature level, analysis timestep model data from the European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA) 40 programme from September 1957 to August 2002.

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 analysed potential temperature level data on a reduced N256 Gaussian grid. Data are available at the 00, 06, 12 and 18 UT analysis times.
