ClimateBench is a benchmark dataset for climate model emulation inspired by WeatherBench. It consists of NorESM2 simulation outputs with asociated forcing data processed in to a consistent format from a variety of experiments performed for CMIP6. Multiple ensemble members are included where available. Data processing scripts and a baseline model example can be found here. Version history 0.1 - Initial release (not including ssp245 data held back for hackathon) 0.2 - Updated release to fix cumulative CO2 concentrations which were calculated incorrectly for future scenarios. 0.3 - Added test data and included a minor fix to hist-aer input data which had misaligned aerosol and GHG data.
