The ISIMIP framework includes bias-corrected climate-input data sets on a 0.5°x0.5°C global grid and at daily time steps. Additional socio-economic and human-influence data are also available, and detailed in the table below.
The methods used for bias correction and statistical downscaling of climate model output have been updated and improved in every ISIMIP phase. See ISIMIP3b Bias Correction, ISIMIP2b Bias Correction and Fast-Track Bias Correction for information about the methods used in the different ISIMIP phases.
For the ISIMIP3 simulation round, the protocol newly includes a counterfactual “no-climate change baseline” (detrended climate + observed socio-economic forcing) to allow for the detection and attribution of observed impacts according to the WGII-AR5 Chapter 18 definition.
If published input data sets for any reason need to be replaced or updated, you will find details of these changes in the input data change log below.
