 The statistical bias correction method developed for ISIMIP is a modification of the transfer function approach applied in the water model intercomparison project, WATER-MIP. It is designed to preserve the absolute changes in monthly temperatures and relative changes in monthly values of precipitation and other variables needed for ISIMIP. This methodology is used to correct the monthly mean and daily variability around it. While the trends and long-term means are well preserved, limitations remain regarding the adjustment of small-scale features and extreme events. This article was authored by S. Hempel, K. Freeler, L.
