Traces of stochastic precipitation, stochastic potential evapotranspiration, stochastic temperature, and standardized precipitation evapotranspiration index (SPEI) values

There are 100 traces in the simulation. This metadata file is only associated with the first trace (Trace_1), although a similar naming convention is used in each trace folder. .\Reservoir SPEI Results\: This directory contains a folder for each trace (simulation) and each trace folder contains stochastic precipitation, stochastic potential evapotranspiration, stochastic temperature, and standardized precipitation evapotranspiration index (SPEI) values for Grant Devine Reservoir, Rafferty Reservoir, Lake Darling Reservoir, and Boundary Reservoir (a replicate of Rafferty Reservoir). All data are provided with a monthly time step. SPEI is calculated for a number of previous months and for each reservoir a calculation of SPEI was done with a 3-month, 6-month, and 12-month lag. In addition, the average of the 3-month and 12-month lag was taken, the October value of the average SPEI was assumed to be equal to the SPEI on November 1 of each year and subset to one value per year in the stochastic streamflow dataset. Potential evapotranspiration (PET) and precipitation have units of millimeters.
