ERA5 is a reanalysis dataset from the European Centre for Medium-Range Weather Forecasts (ECMWF). It combines satellite and station data into a consistent historical weather record going back several decades.
To improve accuracy, EarthScan bias-corrects climate models using ERA5 data ensuring projections reflect observed local conditions.
ERA5 provides the baseline for comparing historical trends with future projections. It’s essential for validating climate models and enhancing location-specific risk estimates.
