ISIMIP2b protocol now available

Posted on Nov. 7, 2016

We are delighted to be able to share with you the latest ISIMIP simulation protocol, ISIMIP2b. You can download the protocol here.

The protocol has been designed to  scientific basis for the IPCC Special Report on the impacts of 1.5°C global warming. A paper describing the scientific rationale for the scenario design, as well as detailed information about the input data sets is open for discussion in Geoscientific Model Development (recently-accepted discussion paper). The most up-to-date version of the simulation protocol can be accessed on the ISIMIP website under Any changes to the protocol will be documented in the 'change log', which can be found directly below the protocol.

Papers based on ISIMIP2b simulation data

  • There is no restriction to who can write papers using the ISIMIP2b data, so long as the co-authorship rules are followed.  
  • To aid communication, we invite you to let us know if you are planning to write a paper using the ISIMIP2b data, including which data sets you would use for your analyses.
  • Let us know if you are intending to submit ISIMIP2b simulations, so that we can make sure that your data are used in papers where relevant – you can do this by entering your name, email address, model name and sector on this page

Input data
We will announce the release of the input data for the group 1 & 2 experiments in about a week, allowing you to start simulating. We are busily working on finalising the land-use input data for the group 3 experiments, and hope to have them ready before the end of the year. 

The submission and acceptance deadlines for the IPCC Special Report on 1.5°C represent a huge challenge for all of us:
October, 2017: submission deadline for papers to be relevant for the IPCC Special Report

April, 2018: acceptance deadline for papers to be relevant for the Special Report

To allow for enough time for paper preparation prior to these deadlines, we have come up with the following timeline for ISIMIP2b:
1 November, 2016: start ISIMIP2b simulation phase

31 December, 2016: deadline for group 1 & 2 simulations for at leat 1 GCM (to allow analyses scripts to be written)
31 March, 2017: deadline for submission of group 3 simulations for at least one GCM.
31 May, 2017: Deadline for submission of all simulations that should be used in the papers written for the Special Report

Computing Resources
If limited computing resources might hinder you in participating in ISIMIP2b, please get in touch as soon as possible. It may be possible to make use of the new super-computer at PIK to run your model. Should any aspect of the protocol be unclear, please don't hesitate to get in touch.
