Dataset
ECMWF ERA-40: daily monthly average reduced N80 Gaussian gridded pressure level analysis data (ggap)
Abstract
This dataset contains daily monthly average, N80 Gaussian gridded, pressure 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.
