This database contains the daily historical fire weather indices averaged over
21 Alaska Predictive Service Areas (PSAs) at elevations at or below 600m for
1979-2017. All indices were computed using meteorological data from the 20km
dynamically downscaled ERA-Interim reanalysis (http://ckan.snap.uaf.edu/dataset
/historical-and-projected-dynamically-downscaled-climate-data-for-the-state-of-
alaska-and-surrou) The fire weather indices here are:
-Evaporative Demand Drought Index (EDDI) for 1, 15, 52, and 90-day
-Standardized Precipitation Evapotranspiration Index (SPEI) for 1, 15, 52, and 90-day
-Reference Evapotranspiration (et0) used to compute EDDI
-Precipitation minus et0 used to compute SPEI
-Vapor Pressure Deficit (VPD)
-Growing Season Index (GSI) for daily and 21-day moving average
