NorESM2-LM simulation results of a radiatively coupled 1%-CO2 simulation (atmospheric CO2 increases by 1% per year until quadrupling after 140 years, but land and ocean do not 'see' this increase) with additional Ocean Alkalinity Enhancement (OAE) at a rate of 0.14 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).
