Author Raffaele Bernardello, January 2019 ! ! We don't get satisfying mass conservation for passive tracers in NEMO. Drift in total mass is of ! the order of a few thousandths/year. Over a long spinup (thousands of years) this results in a drift of ! several points %. After much researching and asking around it seems we are not the only ones with this problem ! however, we haven't been able to find the reason. We need a workaround in order to run the ocean spinup needed for ! CMIP6. Unlike other tracers, DIC does not have a total mass correction available in PISCES ! code. So we are creating one here. Other tracers (NO3, Alk, PO4) are periodically adjusted in total mass to conserve ! the initial amount. This can't be done with DIC because the spun-up state will be used to run transient simulations ! with increase of atmospheric CO2 and consequent ocean uptake. So, the ocean DIC needs to be trully equilibrated. ! ! Here, we compute the total amount of C in the ocean at the beginning of the leg. Then we do the same at the end ! of the leg. Plus, we consider the accumulated air-sea co2 flux, sedimentation of C and Cal, and river input during the leg. ! The change in internal mass has to equal the sum of sink and sources. The residual is used to compute a homogeneous ! global correction to be applied uniformly everywhere to DIC. ! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !
