First exchange on 19.07.2023
A first exchange took place online on 19.07.2023. The StressRes, KIMoDIs, GW_4.0, iMolch, WaRM and CHARMANT consortia formulated their expectations for collaboration on the cross-cutting topic. Among other things, they mentioned the possibility of exchanging experiences, the use of specialist expertise and the creation of synergies.
In order to bring the participants up to speed on the topic of climate projections and scenarios, the German Weather Service (DWD) gave an overview presentation on climate forecasts and projections at the beginning of the meeting, with particular interest being shown in the current quality check of climate data at the DWD.
After the DWD's presentation, the participating projects presented how they use climate projections and scenarios in their projects and discussed their application together.
At the end of the event, the participants had a lively discussion about a possible standardization of the climate projections used in order to facilitate the comparability of the results from the different regions. It was made clear that a certain degree of flexibility in the application of the methods must nevertheless be maintained in order to do justice to the individual issues of the projects. The topic will be taken up again and discussed in greater depth at a further meeting at the end of 2023 when the results of the DWD quality check are available.
Members of the funding measure will receive more detailed information in the members' area. Registration at https://bmbf-lurch.de/reg.html
Presentation of the current status of quality testing on 03.09.2024
The presentation by Nora Leps from the German Weather Service (DWD) provided good insights into the current discussion on the quality testing of climate simulations. The presentation, which lasted around 15-20 minutes and was followed by a 35-minute discussion round (18 participants from LURCH), highlighted the methodology for quality testing the CMIP5 simulations and gave an outlook on the upcoming CMIP6 data.
The CMIP5 results are already available, but they do not influence the current ensemble as the new generation of climate simulations, CMIP6, is not yet fully integrated.
Next steps:
- As soon as CMIP6 - EURO-CORDEX simulations are published, they will be
Quality checked - Results to be published in fact sheets on the DWD website
Decision criteria for ensemble selection still open, depending on the number of
available simulations; results from the quality check; ... - Further coordination with partners and users
The methodology for evaluating the CMIP5 simulations has already provided important insights, but the full integration of the new data will be crucial to further improve the accuracy and reliability of climate projections. Quality testing plays a crucial role in this.
