<!--!introduction!--> Large ensembles of climate model simulations are key tools for assessing climate risks, separating internal variability from external forcing, and interpreting the observational record. Here we present the plans and production status of a Large Ensemble based on the HadGEM3 (Hadley Centre Global Environment Model version 3) climate model. This 40-member Large Ensemble uses HadGEM3 at the N216 atmosphere resolution (about 60 km at midlatitudes) and at 1/4° in the ocean. All-forcings experiments for the period 1950-2100 are conducted and follow the CMIP6 historical and SSP3-7.0 protocols. This initiative is part of the recently started UK NERC multi-centre project CANARI (Climate change in the Arctic-North Atlantic Region and Impacts on the UK). CANARI aims to advance understanding of the impacts on the UK arising from climate variability and change in the Arctic-North Atlantic region, with a focus on extreme weather and the potential for rapid, disruptive change.
