FAQ For Modelers

I have a climate-impact model, can I participate in ISIMIP?

ISIMIP is organised into simulation rounds, in which all impact models are invited to participate. Participating in ISIMIP means running your climate-impact model according to the ISIMIP simulation protocol, and uploading your simulation data to the ISIMIP archive. This includes making use of the input data, and adhering to the scenario design described in the protocol.

Basic information about participating in ISIMIP is described on the Getting Started page. General information about ISIMIP is available on About ISIMIP.

The first point of contact is the ISIMIP Management Group and the Sector Coordinators in your sector.

For which sectors is there already a simulation protocol in the current simulation round

Simulation protocols for ISIMIP2b are available here for the following sectors (*new sectors):

  • global & regional water,
  • global biomes,
  • forests
  • fisheries and marine ecosystems,
  • agriculture,
  • permafrost,
  • heat-related mortality*,
  • coastal systems,
  • energy supply and demand*,
  • tropical cyclones*
What does it mean to join ISIMIP?

Comprehensive information about what it means to participate in ISIMIP can be found in the How-to-Join ISIMIP document (download). By uploading your simulation results to the ISIMIP server, you agree to the terms described in this document.

What is the current simulation round?

We are currently in the ISIMIP2b simulation phase (start November, 2016). Particular focus is being placed on quantifying the impacts of 1.5°C global warming. The ISIMIP2b simulation protocol can be found here, where there is also a log of changes to the protocol since initial publication

Uploading simulation data

Simulation results should be uploaded to the DKRZ server (the same server where the input data are hosted). Each model has its own folder structure. See this page for detailed upload instructions.

Helpful shell scripts for preparing your data files can be found here.

How can I access simulation data from other models?

As an active contributor to ISIMIP (your model is contributing model runs to the current simulation round), you have access to the simulation data for the current simulation round via the DKRZ server. Find out more information about accessing and uploading data at Output Data.

Where can I find a description of the scientific motivation and workflow for ISIMIP?

The ISIMIP Mission & Implementation Document lays out the scientific motivation for the climate impacts modelling activities within ISIMIP, as well as describing the organisational structure and the general workflow.

Which climate variables are available in the ISIMIP input data sets?

The standard set of climate-input variables are given here. All variables are provided at daily resolution on a 0.5°x0.5° global lat-lon grid.

If your model requires additional variables, get in touch with the ISIMIP Team.

Where do I find the input data for the current simulation round?

All input data sets are listed in the input data table under Getting Started > Input Data & Bias Correction.

Detailed download instructions for input data for each simulation round can be found under Getting Started > Input Data & Bias Correction > Downloading...

FAQ For Researchers

I would like to use ISIMIP simulation data from the Fast Track for my study

All Fast Track data is not available via the ESGF node esg.pik-potsdam.de anymore. Please use the data from ISIMIP2b and later simulation rounds since they are created on the basis of much improved bias-corrected climate models.

Which publications have been written using ISIMIP data?
Where do I find the ISIMIP logos

For presentations, posters etc. you can download the ISIMIP logo on the Press page.

How do I cite the ISIMIP input data

The input data table contains information about each of the input-data sets provided for use under the ISIMIP framework, including which papers should be cited when using these data.

We also ask you to cite the ISIMIP scenario-description paper for the simulation round in which the data were provided.
