What is LH? |

It means constant landuse (I will change "LH" into "LU"). I think it is related to the fact that there is no forest harvesting in the model (logging), which actually should be present already at 1850. |

I suggest : For the 2 degree version change dcs to 550 and c08 to 5.0, dust emission*0.75, sip true, new land initial conditions.. |

@DirkOlivie I'm currently running (#184) with secondary ice = .true. , but with "old" land initial conditions, dust emiss, dcs and c8 vaues. Do you want my to stop the simulation? It has reached 121 years. I'm transferring the data now. Maybe you want to start from year 121? |

Hi @adagj , sorry for not having answered earlier. Yes, maybe it is not needed to prolongue (#184) - but good to have the 120 years. I have started a new 2x2 (with the new land IC, reduced dust, different dcs, c8 and sip on) from year 1 - I hope that is ok. |

This discussion is aimed at giving an overview of on-going and planned NorESM3.0 tuning simulations for the period June-August 2025.
For each experiment, please link to the issue describing the simulation in more detail (https://github.com/NorESMhub/noresm3_dev_simulations/issues), but please give also a short description here.
Type A experiments
These experiments are aimed at investigating specific settings/choices in NorESM3.0 (please list your experiment below). Suggestions for experiments:

- Remark : because the IC (intitial conditions) were still present in user_nl_clm and user_nl_cice, this simulation does not seem to be a continuation of [n1850.ne16pg3_tn14.noresm3_0_beta01.20250704 #184] for land and cice, but started again from the initial conditions. For the ocean it seems ok.
