Output of the sea ice, marine biogeochemistry and physical fields of the last 30 years (year 5571-5600) of a Last Glacial Maximum (LGM) simulation. This simulation was performed with NorESM-OC and includes a sea ice model, ocean circulation model as well as full biogeochemistry with the carbon isotopes (Tjiputra et al., 2020, Geoscientific Model Development). In order to obtain the LGM state, several adjustments were made to the model forcing: 1) use of a glacial atmospheric dust field (Lambert et al., 2015), 2) tuning of the surface salinity restoring (procedure described in Climate of the Past - Morée et al., 2020 and its supplement) 3) adjustment of the land-ocean mask by reducing the ocean volume with ~116m (procedure described in Climate of the Past - Morée et al., 2020 and its supplement), and 4) adjustment of the atmospheric Normal Year Forcing fields to an LGM approximation by applying the atmospheric LGM-PI anomalies of Morée and Schwinger (2020, Earth System Science Data, version 1) to the models original ('pre-industrial') atmospheric forcing. The directory tree is organized in an ice/hist/ folder which contains the monthly sea ice simulation files for all years and an ocn/hist/ which contains annual mean marine biogeochemical (*.hbgcy.*) and physical (*.hy.*) output fields for all years.
