ISIMIP3b: bias-adjusted GCM data replaced

Posted by Stefan Lange on June 19, 2020

A flaw in ISIMIP3BASD v2.3.1 caused bad bias adjustments of all variables except ps, rlds, and tas. The problem is particularly severe for precipitation. The flaw was corrected in ISIMIP3BASD v2.4.1, which was used to re-do the bias adjustment of climate model output for the affected variables. All climate models and climate scenarios are affected. The old data were replaced by the new data on June 19, 2020. Differences between old and new data for the historical climate scenario are shown here for GFDL-ESM4, here for IPSL-CM6A-LR, here for MPI-ESM1-2-HR, here for MRI-ESM2-0, and here for UKESM1-0-LL.
