Fig. 4: GEV distribution parameter estimates and their 95% confidence intervals for annual maximum hail size observation during 1979–2021 using Bayesian approach at 0.25° × 0.25° resolution.
From: Bayesian estimation of the likelihood of extreme hail sizes over the United States

a–c represent the lower, estimated, and upper 95% confidence interval of the location parameters respectively. d–f represent the lower, estimated, and upper 95% confidence interval of scale parameter respectively, and g–i represent the lower, estimated, and upper 95% confidence interval of shape parameter.
