NorESM2-LM simulation results of a pre-industrial control simulation (atmospheric CO2 remains constant at 284.32 ppm) with additional Ocean Alkalinity Enhancement (OAE) at a rate of 0.56 Tmol TA per year. OAE follows the idealized protocol of the CDRMIP OAE experiments (homogeneous addition of TA to the surface ocean between 60S and 70N).
