A Comparison of Moderate and Extreme ERA‐5 Daily Precipitation With Two Observational Data Sets

A comparison of moderate to extreme daily precipitation from the ERA-5 reanalysis by European Centre for Medium-Range Weather Forecasts against two observational gridded data sets, EOBS and CMORPH, is presented. We assess co-occurrence days compare full distributions. The quantified hit rate. An extended generalized Pareto distribution (EGPD) fitted positive at every grid point confidence intervals quantiles compared. Kullback–Leibler divergence used quantify distance between entire EGPDs obtained observations. For exceeding local 90th percentile, mean rate 65% (over Europe) 60% CMORPH (globally). Generally, we find a decrease with increasing intensity. agreement weaker over southern Mediterranean region Iceland compared rest Europe. Differences are smallest oceans. largest NW America, Central Asia, land areas 15°S 15°N. on overlapping sets more than 80% points average. intensity comparisons indicate an excellent Germany, Ireland, Sweden, Finland, disagreement where uses sparse input stations. agree well midlatitudes disagree tropics.
