PRISM_DATASET_REMARKS: This grid was developed in three steps: (1) vapor pressure deficit data were modeled with PRISM at 30-arc-second (~800m) resolution to produce the source grid(s) listed under PRISM_SOURCE_FILENAME, on the date(s) listed under PRISM_SOURCE_CREATE_DATE; (2) These twelve monthly 800m grids were then upscaled to 2.5-arc-minute(~ 4km) resolution with a Gaussian filter; and (3) The resulting twelve monthly 4km grids were averaged to obtain a 4km mean annual vapor pressure deficit grid.
