Abstract

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). Within the Bolin Centre's awarded strategic government grant to strengthen the research area of climate modelling more than 10 new positions have been funded in the Centre, seven at senior faculty level. Most recently, in 2023, four postdocs where recruited, in the four research themes of the Bolin Centre. 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 high performance computational resources, as well as on specific software, in terms of advanced computer codes developed or maintained and refined at the three applying centres. Codes used range from global climate models to fine-scale regional or local models. 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. 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. The second official Earth System Model used within the Bolin Centre is the Norwegian Earth System Model (NorESM), whose development based in Norway Bolin Centre scientistst are closely involved with,. In addition to these Earth system models a number of other codes covering a range of complexities is used by our researchers to complement the studies with the comprehensive global models.
