There are five global climate models (GCM), each with four carbon evolution scenarios supported by ISI-MIP5 (Inter-Sectoral Impact Model Intercomparison Project). These daily data cover the 1950–2099 and have a resolution of 0.5°. They have been reformatted from NetCDF into ready-to-use SWAT-formatted text files.

Detailed of the data and their use in an application in Califonia are given in articles from "Nature Scientific Data" and "Environmental Modelling & Software":
