Daily 2 P.M. Average Relative Humidity Time Series Maps and Point Data for State of Hawaii

This dataset contains time series maps of daily 2 p.m. average terrestrial relative humidity for four counties of the State of Hawaii spanning the time period from Jan. 1. 2002 through December 31, 2025 with a uniform spatial resolution of 250 m. x 250 m. Each map in the data_maps folder represents one day of 2 p.m. gridded relative humidity (representing the averaged relative humidity from 1:00 p.m. through 1:59 p.m.), provided in GeoTiff raster format containing one data layer and a corresponding land-sea mask layer. Point data time series of the 2 p.m. averaged relative humidity for all weather stations which reported data on each day of the time series associated with the maps are included as column-separated value (CSV) tables, as well as CSVs of corresponding leave-one-out cross-validation metrics for the maps with respect to the observed data. The maps are derived by using a multi-adaptive regression spline model to spatially interpolate the observed weather station point data to the map grid. These data are intended to support any research or applications that require spatially-continuous, high resolution relative humidity data in the State of Hawaii.
