Abstract
This dataset contains 1.5 degree gridded, analysis time step wave model data from the European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA) 40 program from September 1957 to August 2002. ERA-40 followed on from the ERA-15 re-analysis project. These data are GRIB formatted.
