This simulation protocol contains all information necessary to run climate-impacts simulations consistent with other models participating in the ISIMIP2a simulation round. The protocol is divided into 15 chapters: chapters 1-5 contain important information for modellers in all sectors. Chapters 6-14 provide sector-specific instructions (can be downloaded separately below, including the references) and chapter 15 contains the references. For any queries, get in touch.
The latest version of this protocol was released on Feb. 28, 2020 and is known as the ISIMIP2a-extended protocol.
The ISIMIP2a-extended protocol is very similar to the ISIMIP3a protocol, circulated on Feb. 21, 2020, and we suggest to prioritize simulations for ISIMIP3a and 3b over ISIMIP2a-extended. However, we still encourage all impact modeling teams to consider performing simulations according to this ISIMIP2a-extended protocol – even if you have already contributed simulations to the original ISIMIP2a round. These simulations will enhance the basis for evaluating the models that were used for the future projection runs in ISIMIP2b, which have been widely used and will continue to be of great value.
