Reference and future periods // Water demand projections uploaded to DKRZ server

Posted on Nov. 2, 2012

1. Reference and future periods

First of all, please make sure you adhere to the reference period 1980-2010 which is defined in the protocol so that comparability across results is guaranteed.

Please fill the year from 2005 to 2010 by the associated RCP (depending on the future simulations you consider). That is different from our previous announcement where we asked you to fill the reference period with RCP4.5 simulations. We noticed that that will create problems for GCMs where you do not simulate RCP4.5. This rule applies to the global mean temperature data as well as to your impact indicators.

For future periods we suggest you use the time slices for the time periods as described in the simulation protocol on page 12 ->  Section 5.1: Reporting and reference time periods.

As of Monday, 5  November 2012 the above changes will also have been incorporated into the protocol, so please make sure you check our website ( -> Simulation protocol) then.

2. Water demand projections uploaded to DKRZ server

The Watergap and H08 modeling teams have begun uploading their water demand calculations (water withdrawals and consumption) to the server in Hamburg. You are invited to use these calculations for your own model simulations and analyses.

Please do not hesitate to get in touch with us in case you have questions or comments.
