Bias-corrected VIC historical runoff data (1950-2013) for the Central Sierra Nevada

In most cases, bias correction of the runoff data at daily scale was performed in the upper subbasins, where most of the precipitation occurs. Therefore, the bias correction increased the amount of water available in the upper subbasins, increasing the NSE but also causing a positive bias. Due to the lack of gauges, to balance out this extra water the available water in the lower watersheds was reduced evenly by regression, to maintain a total basin-wide bias close to 0%.
