Gridded historical downscaled large-ensemble natural forcing global model data


50 realisations of CanESM2 with no GHG forcings were statistically downscaled onto the 300 arc second (~10km) ANUSPLIN grid (McKenney et al., 2011) using the Bias-Corrected Constructed Analogues with Quantile mapping reordering (BCCAQ) algorithm (Werner and Cannon, 2016) to produce daily climate surfaces for 1961-2100. Each day in the 300 arc second (~10 km) grid was first spatially-disaggregated using a local lapse rate upsampling algorithm (Wang et al., 2006), and the entire dataset was then bias corrected so that 1971-2000 climatological monthly means matched the Pacific Climate Impact Consortium PRISM climatology To avoid discontinuities at the boundaries between months, monthly climatologies were smoothed to daily climatologies following Epstein (1991) before bias correction.
