Crosscutting Activities (CC) in PalMod phase II create a platform that is dedicated to research and services to support and connect the working groups 1-3. Fig. 1 (part I of the Pre-Proposal) depicts the overall structure of CC and their linkages to the other work packages. The work proposed in CC will on the one hand help to advance the modelling efforts and on the other hand yield insight into the interpretation and evaluation of the model results. The two major aspects that CC will cover are development and optimization of the models or model components used in PalMod (CC.1), and data management, model-data evaluation & hypothesis testing (CC.2). These are essential research activities and overarching building blocks for the success of PalMod. They are particularly important for model development and optimization tasks of the project because they will enable the ambitious simulation of a full Glacial cycle, as well as for the model-data evaluation and the hypothesis testing connected to these simulations.


CC.1 Model coupling and runtime optimisation

Principal Investigators: H. Bockelmann (DKRZ), D. Barbi (AWI), NN (MPI-M), T. Slawig (CAU), R. Winkelmann (PIK)
To reach the overall project goals by improving model capabilities and runtime, CC.1 will focus on the dynamic coupling of processes that take place at the interface between land/ice sheets and the ocean in simulations with dynamic and transient boundary conditions, particularly for paleo-lakes, continental shelves and ice shelf cavities. For the implementation aspect of the models we aim for higher computational throughput of the full Glacial cycle simulation at coarse and low resolution by improved parallelism and adaption of the source code to recent and upcoming HPC architectures.


CC.2 Data Management & Model-Data Comparison

Principal Investigators: H. Thiemann (DKRZ), K. Rehfeld (UHD), O.Bothe (HZG), A. Hense (U Bonn), NN (GEOMAR)
To facilitate the data management and the data-model intercomparison, CC.2 aggregates and standardizes the modl output of the ESMs. Furthermore, it is responsible for the data stewardship of the proxy syntheses, and provides a centralized location for model intercomparison, simulation archiving and publication. Moreover, new metrics and tools will be developed to compare model and data within PalMod, which enables evaluation of the simulations, and the testing of the key hypotheses on Glacial-interglacial climate dynamics.
