This is a proposal for the continuation of the project described in NAISS 2023/6-387 which originates in SNIC 2019/12-18. It is an Earth System Modeling project (Comprehensive Climate Model) including several individual models describing the atmosphere, ocean, land surface, vegetation, and carbon cycle. The storage capacity required for a single 150 year simulation is in the order of about 20 TB. Including for example the chemistry, the output data is in the range 8 GB/month. In the framework of the projects RESCUE and OptimESM we are currently simulating a series of in total 14 simulations of various length (5 RESCUE plus 9 OptimESM) over the course of the next six months with an estimated total of about 190TB. For post-processing and evaluation the data will be kept on SWESTORE and the NAISS large storage (NAISS 2024/4-9) for fast access. After evaluation and postprocessing have been performed the final, cmorised data-sets will be uploaded to a project storage for OptimESM. At the same time we will perform test and calibration simulations in the run up to the coming CMIP7 Fast Track simulations for the next IPCC Assessment Report (AR7). Therefore, further access of SWESTORE-storage is of vital importance to the Earth-System modelling group in the coming years. Aside from the two projects mentioned above, there are two additional ongoing EU-projects that have emerged directly from work based on SNIC 2019/12-18 and its successors: GreenFeedBack and AI4PEX. These projects will benefit greatly from a continuation as the amount of data will increase over time. While CMIP7 related data will be stored on data-servers of the ESGF (Earth System Grid Federation) after having been processed and evaluated and, thus, removed from SWESTORE, we anticipate that the amount of storage will be needed for the duration of the whole CMIP7 process which is likely to not finish before 2028. We estimate, that the 100 TiB we currently use in combination with the NAISS large-storage (NAISS 2024/4-9) will be sufficient over the coming year and will likely need an extension into the coming year.
