ECMWF ERA-40: reduced N80 Gaussian gridded potential vorticity level analysis data (ggav)
Abstract
This dataset contains N80 Gaussian gridded, potential vorticity level, analysis timestep parameters 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. Access limited to UK based academic researchers only. These data are GRIB formatted.
