Welcome to the ISIMIP Repository

Here you will find data relating to the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP). Use of these data are subject to the ISIMIP terms of use. Documentation of the impact models that provided impact simulations for this archive can be found in the ISIMIP Impact Model Database.

You can use any specifier from the ISIMIP protocols, e.g. "qtot", "water_global", "rcp26", "climate", "water_global", etc. You can also directly use the advanced search interface.
