This application is intended to provide the whole Bolin Centre for Climate Research at Stockholm University with storage space for climate modelling. Founded in 2006, the Bolin Centre for Climate Research is a multi-disciplinary consortium of researchers led by Stockholm University that conducts fundamental research on critical processes in the climate system. The research program strives to understand natural climate evolution and variability, as well as changes imposed by the increasing human impact on the Earth System. It aims to build next generation expertise and knowledge on climate-influencing processes, over a range of time-scales and subsystems while addressing related societal issues. The challenge is to effectively harness national scientific expertise in a growing international effort to understand, mitigate and adapt to climate change. The Bolin Centre consists of scientists from the Departments of Meteorology, Environmental Science and Analytical Chemistry, Physical Geography, Geological Science, Ecology, Environment and Plant Sciences and Zoology at Stockholm University as well as FLOW at the Royal Institute of Technology (KTH) and the Rossby Centre at the Swedish Meteorological and Hydrological Institute (SMHI). We have a large number of individual research applications using climate models involving the majority of the staff at Bolin Centre for Climate Research. These research areas rely heavily on access to substantial storage capacity connected to high performance computational resources, as well as on specific software, and advanced computer codes developed or improved at the three applying centres for postprocessing of climate model data. The EC-Earth climate model is today used in a number of applications here at the Bolin Centre and is our main tool in studying the climate. The second official Earth System Model used within the Bolin Centre is the Norwegian Earth System Model (NorESM) . In addition to these Earth system models a number of other codes ranging in complexity is used by the researcher to complement the studies with the comprehensive models. It is hence of vital importance for all our research that we continue to have access to large storage capacity. The Bolin Centre has been awarded a strategic government grant to strengthen the research area of climate modelling. These funds have led to more than 10 new positions in the Centre, seven at senior faculty level. As part of the EC-Earth consortium, we, at the Bolin Centre for Climate Research in collaboration with the Rossby Centre at SMHI, have implemented the EC-Earth model on the Triolith and Tetralith super computers. This storage project is intended for storage of data produced in the large computing project Climate Modelling at the Bolin Centre for Climate Research (SNIC 2019/1-2) and submitted together with the application for the Large computing project SNIC 2020/1-31.
