A gridded annual runoff dataset from 1982 to 2016 for Peru

A gridded annual runoff dataset from 1982 to 2016 has been developed using PISCO dataset: streamflow, precipitation, and potential evapotranspiration (from temperature using Hargreaves-Samani). A probabilistic Budyko approach was used to estimate runoff using 14 spatial clusters where an empirical distribution of omega (Fu's parameter) was fitted to the data. In this sense, a maximum, mean, and minimum value is given for runoff in each grid.

Figure. Example of the estimation of runoff for the Pativilca and Lacramarca basins. The average value is appreciated as a black line and associated uncertainty (maximum and minimum) as gray color, of the probabilistic Budyko.
