A boxplot showing the range of estimates per year given the set of competing models for a) wet season and b) dry season for Hilo station. The blue solid line represents the actual seasonal rainfall at Hilo station for each year and the red dotted line represents the estimate from the Elison Timm et al. (2015) model.
