ERA5 and MERRA-2 reanalysis data wind speeds are commonly used in wind energy resource assessments to predict long-term wind speeds for short-term data collection campaigns. Recent ArcVera analysis as well as due diligence review of third-party reports suggests the potential for discontinuity in interannual variations for each data source, which can introduce significant bias if not treated with proper consideration.
