Task 1.5 System and preparation of products relevant to user groups

This task will coordinate the data flow, and host the exclusive storage for the standardised data from the hindcast ensembles for a fast and convenient application. The data strategy will be developed and set up together with DWD, splitting into short- and long-term data, which can be either moved to DWD or archived in the long-term archive system of DKRZ. The results of Coming Decade will be directly incorporated into the further development of the central processing and evaluation system for ICON-XPP , in close coordination with the post-processing (Task 2.2) and the product development (Task 2.3). The Coming Decade Evaluation System (CODES) platform builds via the Freva framework (Kadow et al. 2021) on the high performance computer at DKRZ will offer direct access to the seamless model results, evaluation of several development stages. Data pools such as CMIP6/DCPP, MiKlip, ERA5 and more at the DKRZ will be made available within the Coming Decade system. Software tools of other projects (e.g. ClimXtreme, Regiklim, and notably MiKlip) and project partners (e.g. DWD MAVIS (Meteorological Analysis and VIsualisation Software)) will be technically and scientifically updated and incorporated as plugins in the Coming Decade system from the start of the project. Coming Decade's Open Source Software plugins as developed in Task 2.2 & 2.3 will be supported, improved, and packaged for a clear validation. One annual to decadal evaluation package will be (further) developed for the main validation of the hindcast systems, as produced in WP1. This package will be set up at DKRZ to be transferred to DWD at the end of Coming Decade.

In this task all developments available by mid-2024 will be integrated into the pre-operational ICON-XPP forecasting system prepared in cooperation with the ICON-Consortium (initial ICON-Seamless). From 2025, these developments will already enhance the operational system. The further scientific achievements will be implemented in the next model generation (refined ICON-Seamless) to the end of Coming Decade and will be used in routine operations around 2027. Userrelevant climate services are developed after intensive exchange with users, e.g. at the annual user workshops, and are regularly taken over into routine operation after their scientific evaluation. This transfer takes place in close cooperation with Tasks 1.3, 1.6, 2.2, and 2.6.
