It\u2019s difficult to produce a good quality map that captures the extreme gradients and spatial variability of rainfall in the islands. To overcome this obstacle, a new method has been developed by Matt Lucas from the Water Resources Research Center at Â鶹´«Ã½to create maps using an optimized geostatistical kriging approach. A key finding is that optimization of the interpolation approach is necessary because maps may validate well (low errors) but have unrealistic spatial patterns.<\/p>\n\n\n\n<p>A paper describing these methods was recently published in the Journal of Hydrometeorology (<a href=\"https:\/\/journals.ametsoc.org\/view\/journals\/hydr\/23\/4\/JHM-D-21-0171.1.xml\" target=\"_blank\" rel=\"noreferrer noopener\">Optimizing Automated Kriging to Improve Spatial Interpolation of Monthly Rainfall over Complex Terrain<\/a>).<\/p>\n\n\n\n<p>These methods are currently being used to produce the monthly rainfall maps that are available for visualization and download in the Hawai\u2018i Climate Data Portal.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mapping rainfall over the complex topography of Hawai\u2018i is not easy.
