Simulation Protocols

The ISIMIP2b scenarios are designed to elicit the contribution of climate change to impacts arising from low-emissions climate-change scenarios. Pre-industrial control runs are included to facilitate statistical comparison with a no-climate-change case.

The ISIMIP2b protocol covers several new sectors, including tropical cyclones, temperature-related mortality and lakes.

The scientific rationale for the scenario design is documented in a GMD discussions paper by Frieler, et al.

Please read the data and co-authorship policy and register your model for ISIMIP2b here.

Below you will always find the latest version of the simulation protocol. Changes compared to previous versions will be recorded in the change log.

• Important information about preparing your simulation files can be found here.
  

Information about which input data are available can be found here.

• Basic analysis of global-mean-temperature levels in the ISIMIP2b climate data can be found here.
  

The simulation protocol contains all information necessary to run climate-impacts simulations consistent with other models participating in the current ISIMIP simulation round, ISIMIP2a. Here you will find the protocol for ISIMIP2a. Click on the link below for information about the ISIMIP Fast Track.

Important information about preparing your simulation files

The protocol is divided into 7 chapters: chapters 1-6 contain important information for modellers in all sectors. Chapter 7 provides sector-specific instructions (can be downloaded separately below). For any queries, get in touch.

See the table below for an up-to-date list of protocol changes.
