Statistics of bias-corrected RCM outputs and SWAT simulated streamflows forced by the observed climate variables and bias-corrected RCM outputs.

Statistics	NS	PBIAS
“RCM simulated precipitation with bias correction”^a
Validation period 1990~2005 (daily)^b
Validation period 1990~2005 (monthly)
“RCM simulated maximum temperature with bias correction”^a
Validation period 1990~2005 (daily)
Validation period 1990~2005 (monthly)
“Streamflow simulated with observed meteorological data”
Calibration period 1986~1989 (daily)
First validation period 1990~2002 (daily)
Second validation period 1986~2005 (monthly)
“Streamflow simulated with bias-corrected RCM outputs”
Validation period 1990~2002 (daily)
Validation period 1986~2005 (monthly)

Bias correction methods used are quantile mapping for precipitation and distribution mapping for temperature [19].
^b“Daily” or “monthly” in the brackets means the time step used to calculate the statistics.
