Data for Asessing the Temporal Stability of Gridded Precipitation Products in the Southeastern United States
Description
These data enable an assessment of discontinuities and associated bias in annual trends of precipitation totals for the southeastern United States from high-resolution, gridded products and combinations of the products. The products are Daymet, gridMET, nClimGrid, PRISM AN, PRISM LT, and TerraClimate. Daymet, nClimGrid, and PRISM AN have both daily and monthly totals. PRISM LT and TerraClimate only have monthly totals. gridMET only has daily totals. The time period is 1980-2024. The data files are described below. 1. ReferenceGauges_Missing.xlsx -- Monthly precipitation totals from the 120 COOP gauges that produced the reference time series. Missing totals are blanks. 2. ReferenceGauges_SeriallyComplete.xlsx -- Monthly precipitation totals from the 120 COOP gauges that produced the reference time series. Missing totals were replaced with the mean total from the three nearest gauges. 3. ReferenceGauges_Location&Elevation.xlsx -- The latitude, longitude, and elevation of the 120 COOP gauges. 4. AnnualTotals_from_MonthlyProducts.xlsx -- Annual totals from reference-gauge network, Daymet, nClimGrid, PRISM, TerraClimate, and all possible combinations of products 5. AnnualTotals_from_DailyProducts.xlsx -- Annual totals from reference-gauge network, Daymet, gridMET, nClimGrid, PRISM, and all possible combinations of products 6. Daymet_Gauges.xlsx -- Gauges in the southeastern United States used to produce Daymet estimates 7. nClimGrid_Gauges.xlsx -- Gauges in the southeastern United States used to produce nClimGrid estimates 8. PRISM_Gauges.xlsx -- Gauges in the southeastern United States used to produce PRISM estimates 9. TerraClimate_Gauges.xlsx -- Gauges in the southeastern United States used to produce TerraClimate estimates 10. ASOS.xlsx -- ASOS (Automated Surface Observing System) gauges in the southeastern United States 11. Gauges_120.shp -- Shapefile containing the 120 COOP gauges. The files are located in the GIS archive. 12. SEUSA.shp -- Shapefile containing the southeastern United States without state borders. The files are located in the GIS archive. 13. SEUSA_NoHighElevations@SEUSA_NoHighElevations@30arcseconds.shp-- Shapefile containing the southeastern United States with high-elevation areas removed. The removal was performed using a DEM with 30 arc-second resolution. The files are located in the GIS archive. 14. SEUSA_NoHighElevations@1km.shp-- Shapefile containing the southeastern United States with high-elevation areas removed. The removal was performed using a DEM with 1-km resolution. The files are located in the GIS archive. 15. SEUSA_NoHighElevations@4km.shp -- Shapefile containing the southeastern United States with high-elevation areas removed. The removal was performed using a DEM with 4-km resolution. The files are located in the GIS archive. 16. SEUSA_40kmCells.shp -- Shapefile containing 40-km grid cells that cover the entire southeastern United States. The files are located in the GIS archive.
