Idaho Temperature-Derived Metrics (Frost-Free Days & Growing Degree Days) sum (1980-2022)

Annual sum of frost free days (FFD) in the state of Idaho between 1980 and 2022. These data were processed by ISU's GIS TREC with source data from the DAYMET dataset. https://daac.ornl.gov/DAYMET/guides/Daymet_Daily_V4R1.html Note: The frost free days (daily Tmin > 0° C) do not need to be consecutive to be included in this analysis. Annual sum of growing degree days (GDD) in the state of Idaho between 1980 and 2022. These data were processed by ISU's GIS TREC with source data from the DAYMET dataset. https://daac.ornl.gov/DAYMET/guides/Daymet_Daily_V4R1.html Note: GDD was calculated using a base temperature of 0° C following the methodology described here https://www.canr.msu.edu/uploads/files/Research_Center/NW_Mich_Hort/General/CalculatingGrowingDegreeDays.pdf
