Publication summary: 

Spatial patterns of rainfall in Hawai‘i are among the most diverse in the world. Utilizing a high-resolution gridded data set of monthly and annual rainfall for Hawai‘i from 1920 to 2012, seasonal and annual trends were calculated for every 250-m pixel across the state and mapped to produce spatially continuous trend maps. To assess the stability of these trends, a running trend analysis was performed. The results show widespread drying across the state, and reveal the spatial patterns and timing of upward and downward trends.
