Second phase of the BMBF joint project NUKLEUS has started

The joint project "Useable Local Climate Information for Germany 2 (NUKLEUS2)" will also be one of two cross-sectional projects in the second phase of the RegIKlim funding measure. The central task of the cross-sectional projects will be the conceptual design and development of a climate register. NUKLEUS2 will primarily carry out the work on the basis of the climate register. In addition to the provision of climate data, the evaluation and quality assurance of the underlying climate simulations, including the bandwidths and uncertainties in comparison with the global and the emerging European CMIP6 ensembles, is central. The data itself is made available via the data and analysis portal Freva. Freva also offers the possibility of integrating useful tools for standardised data preparation as so-called Freva plugins and thus acts as an interface to the impact models of the model regions. Building on the findings from the first funding phase and the results of the other work packages, this interface is to be further optimised and standardised.

The focus of the sub-project of the Dresden Univesrity of Technology (TUD) is the optimisation of interfaces in order to bring the quality-assured climate data of the NUKLEUS model ensemble together with required geodata, e.g. on land use, into the application in an accurate and harmonised form. This focus is being worked on in a work package under the leadership of TUD. Essential aspects are the support of the model regions and the cooperation with the users in the use of the NUKLEUS2 data for impact models. The quantification of uncertainties in the model chain from climate to impact models is a technical focus of the TUD sub-project. Furthermore, TUD will participate in the conception and prototypical implementation of the climate register.
