Ensemble of MPI-ESM1-2-HR CMIP6 historical simulations without solar and ozone variability (i.e., set to the year 1850). The simulations are performed within the BMBF project "Solar contribution to climate change on decadal to centennial timescales" (SOLCHECK) of the "Role of the middle atmosphere in climate" (ROMIC II: https://romic2.iap-kborn.de/en/romic/strategy). The experimental setup is identical to the MPI-ESM1-2-HR historical CMIP6 simulations except for the solar and ozone variability. Please refrain from using the following variables since their computations where either erroneous or do not comply with the CMIP6 protocol: Eyr_fracLut, 6hrPlevPt_sfcWind, Amon_mc, CFday_mc, CFmon_dmc, CFmon_smc, CFmon_mcd, CFmon_mcu, Omon_o2sat, Oyr_o2sat, Omon_uo, Omon_umo, Omon_hfx Omon_tauuo Technical details: Ensemble run on bullx B700 Mistral at DKRZ

Ensemble of MPI-ESM1-2-HR CMIP6 historical simulations with low-pass filtered solar and ozone variability (i.e., using a 33-years running-mean).

The experimental setup is identical to the MPI-ESM1-2-HR historical CMIP6 simulations except for the solar and ozone variability.

This datasets contains simulation output for the global hydrological models HydroPy and MPI-HM. Both used meteorological forcing from the GSWP3 dataset for the period 1979-2014 and a 50 years spinup period. The analysis of this simulations is published at https://doi.org/10.5194/gmd-2021-53 .

RCM forcing data from two realisations of the CMIP5 experiment historical. The historical experiment covers the period 1850-2005. Forcing data are available from 1949 to 2005 only. The realisations differ with respect of their branch times of the pre-industrial control run (piControl): historical_r1i1p1 started end of 1849, historical_r2i1p1 started end of 1900 .

RCM forcing data from three realisations of the CMIP5 experiment historical. The historical experiment covers the period 1850-2005. Forcing data are available from 1949 to 2005 only. The realisations differ with respect of their branch times of the pre-industrial control run (piControl): historical_r1i1p1 started end of 1879, historical_r2i1p1 started end of 1979 and historical_r3i1p1 started end of 1920.

nuArctic aims at increasing our understanding of the remineralization of nutrients and carbon in the Arctic Ocean and its feedbacks with the Earth System, i.e. the capacity of the Arctic Ocean to be productive and to act as a carbon sink into the future. To do so, the project is proposing modeling advances to increase the robustness of model projections. This project includes global model simulations with the global multi-resolution Finite Volume Sea Ice-Ocean Model (FESOM version 2.1) coupled to the Regulated Ecosystem Model (REcoM version 3, Gürses et al. 2024). For this project, model simulations include a representation of terrigenous inputs from both rivers and coastal erosion and were run from 1970-2100 on a model grid with eddy-permitting (4.5 km) resolution at pan-Arctic scale. The ocean-only model simulations were forced at the ocean surface with 3-hourly atmospheric output from the AWI Climate Model (Semmler et al. 2020). The project includes model experiments under four “Shared Socioeconomic Pathways” emission scenarios, a control run and sensitivity experiments. This work lead to the publication of Oziel et al. 2025 ("Climate change and terrigenous inputs decrease the efficiency of the future Arctic Ocean’s biological carbon pump » in 2025 in Nature Climate Change) which comprises a detailed description of the methods, model experiments and setups but also a publication of the source code and post-processing scripts (Oziel, 2024).

historical is an experiment of the CMIP5 - Coupled Model Intercomparison Project Phase 5 ( https://pcmdi.llnl.gov/mips/cmip5 ). CMIP5 is meant to provide a framework for coordinated climate change experiments for the next five years and thus includes simulations for assessment in the IPCC AR5. This subset of the CMIP5 additional historical data were collected by ETH Zurich until 15th March 2013 in support of IPCC AR5 Working Group 1 ( http://wiki.c2sm.ethz.ch/COSMO/CMIP5 ). These data are part of the IPCC-DDC AR5. historical (3.2 Historical) - Version 2: Simulation of recent past (1850 to 2005). Impose changing conditions (consistent with observations).
