Rainfall Time Series

This project rainfall patterns over space and time, working with monthly rainfall interpolated from 1067 rain gauges over the period 1874-2007, collated from the Rainfall Atlas of Hawai'i. The Hawaiian Islands have one of the most spatially diverse rainfall patterns on the earth. Rainfall patterns will be organized into multiple pyramid frameworks to search for monthly and annual anomalies concealed at different spatial and temporal scales. Each time period will be stored within a data pyramid, and pyramids will be aggregated in a triangle framework to traverse time intervals. Interactive visual tools will be developed to analyze anomalies emerging for a progression of threshold values, essentially creating a data brushing capability based on spatial, temporal and spatiotemporal queries.
