This dataset contains ensemble output from 30 historical simulations produced with the computationally efficient version of the Norwegian Earth System Model version 1 (NorESM1-F). The simulations use CMIP5 historical forcings before 2005 and then RCP8.5 scenario forcing. The temporal coverage is 1850-2030. The raw model output is provided in netcdf format and contains in-file metadata covering field names, units, space and time information.
