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