Select Variable(s):

Variables with Time coordinate t

PRISM_pet_norm = Accumulated potential evapotranspiration using Hargreaves Equation for given duration using PRISM monthly normal MaxT/MinT
gamma_PRISM = Location parameter (gamma) of Log-Logistic distribution calculated using PRISM normal as M0, and station-based alpha and beta parameters.
pet = Accumulated potential evapotranspiration using Hargreaves Equation for given duration using PRISM daily MaxT/MinT
spei = SPEI based on log-logistic dist from H and W (1996). Uses PRISM-based location parameter.
