Optional information

(additional information, if the experiment is branched/hybrid restart from previous parent experiment; you may find more information relevant to the experiment_id here: https://github.com/NorESMhub/noresm2cmor/blob/master/tables/CMIP6_CV.json)

These are continuations of the three first ensemble members of esm-ssp245

There already exis some NorESM2-LM experiments for the years 2101-2299 (e.g. #339) with different treatment of the aerosol emissions. They use constant anthropogenic aerosol emissions after 2100, following O'Neill 2016 (https://gmd.copernicus.org/articles/9/3461/2016/) while in these simulations we change the aerosol emissions following Meinshausen 2020 (https://gmd.copernicus.org/articles/13/3571/2020/) which is a linear phase out of non-biomass aerosols by 2250. The biomass aerosols are kept constant from 2100 and onward. I therefor suggest we name these 3 members with f2 as forcing realization
