Model version I (left) vs. Model version II (right)

Presenting annual means (from monthly climatological means) from simulations with the following casenames:

ModI = n1850.ne30_tn14.hybrid.20240822
ModII = N1850frc2.f09_tn14_checkaer2.3.20240909


MG2, CLM5, Eul gas deposition scheme, and both using CMIP6 emissions and PD oxidants for PI.

ModI is from a simulation using NorESM2.5, both land and atmosphere on a SE grid and increased number of vertical coordinate
1850 conditions
ModII is from a NorESM2.3 simulation, with refactored code but without any aerosol parameterisation changes compared to 2.1
1850 conditions
