PRISM 800-meter Meteorological Variables at Population-Weighted Zip Code Tabulation Areas

We aggregate 800m estimates of daily temperature (minimum, mean, and maximum) and total precipitation from Parameter-elevation Regressions on Independent Slopes Model (PRISM) to the zip code tabulation area (ZCTA). We first aggregate the raw raster files from PRISM to the census block based on areal weighting, and then apply a 2010 census block to ZCTA crosswalk to population weight from the census block to the larger ZCTA area. National ZCTA-level temperature and precipitation are provided for 2010 zip code tabulation area geographies. From the PRISM website (https://prism.oregonstate.edu/): The PRISM Group gathers weather observations from a wide range of monitoring networks, applies sophisticated quality control measures, and develops spatial datasets to reveal short- and long-term weather patterns. The resulting datasets incorporate a variety of modeling techniques and are available at multiple spatial/temporal resolutions, covering the period from 1895 to the present. Whenever possible, we offer these datasets to the public, either free of charge or for a fee (depending on dataset size/complexity and funding available for the activity). We have aggregated from the native raster format to the ZCTA for use in health analyses which often rely on zip code level data. Further crosswalk from the ZCTA to zip code will be required for this use. For more information, see: https://github.com/Climate-CAFE/zip_codes_and_zctas.
