Abstract

This dataset contains 6-hourly monthly average , T159 spherical harmonics gridded, pressurel level, analysis timestep data from the European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA) 40 program from January 1958 to December 2001. ERA-40 followed on from the ERA-15 re-analysis project. Access limited to UK based academic researchers only. These data are GRIB formatted.
