NEW Interactive Rainfall Atlas of Hawaii

The Rainfall Atlas of HawaiʻI Web site is a creation of the UH Manoa Department of Geography. It is a set of maps of the spatial patterns of rainfall for the major Hawaiian Islands. Maps are available for mean monthly and annual rainfall covering  the 30 year period 1978–2007.

The interactive map allows users to see the patterns of mean monthly and annual rainfall and corresponding uncertainty, zoom in on areas of particular interest, navigate to specific locations with the help of a choice of different base maps, and click on any location to get the mean annual rainfall and a graph and table of mean monthly rainfall. The locations of stations can also be shown on the interactive map. Clicking on a station gives both station and mapped estimates of monthly rainfall along with station metadata.

Rainfall maps can also be downloaded in various forms.

Rainfall measurements taken at over 1,000 stations were used as the principal source of information in the development of the rainfall maps. Files containing estimated mean monthly and annual rainfall and uncertainty for each station used in the analysis are available for download. A file with information on each station, including the name, observer, location, elevation, and period of record, is also available.

This is a fabulous resource for a wide variety of types of research. Check it out!
