“…A state estimation framework that combines observations with a state-of-the-art numerical model, while strictly adhering to the underlying conservation equations, can help infer the mechanisms responsible for changing heat, salt, and freshwater budgets. Currently available ALPS data have been heavily utilized within the ECCO framework to improve estimates of the time-evolving global ocean-sea ice state on decadal time scales (Wunsch and Heimbach, 2013;Forget et al, 2015a).…”

Abstract. The Ocean Model Intercomparison Project (OMIP) is an endorsed project in the Coupled Model Intercomparison Project Phase 6 (CMIP6). OMIP addresses CMIP6 science questions, investigating the origins and consequences of systematic model biases. It does so by providing a framework for evaluating (including assessment of systematic biases), understanding, and improving ocean, sea-ice, tracer, and biogeochemical components of climate and earth system models contributing to CMIP6. Among the WCRP Grand Challenges in climate science (GCs), OMIP primarily contributes to the regional sea level change and near-term (climate/decadal) prediction GCs.OMIP provides (a) an experimental protocol for global ocean/sea-ice models run with a prescribed atmospheric forcing; and (b) a protocol for ocean diagnostics to be saved as part of CMIP6. We focus here on the physical component of OMIP, with a companion paper (Orr et al., 2016) detailing methods for the inert chemistry and interactive biogeochemistry. The physical portion of the OMIP experimental protocol follows the interannual Coordinated Ocean-ice Reference Experiments (CORE-II). Since 2009, CORE-I (Normal Year Forcing) and CORE-II (Interannual Forcing) have become the standard methods to evaluate global ocean/sea-ice simulations and to examine mechanisms for forced ocean climate variability. The OMIP diagnostic protocol is relevant for any ocean model component of CMIP6, including the DECK (Diagnostic, Evaluation and Characterization of Klima experiments), historical simulations, FAFMIP (Flux Anomaly Forced MIP), C4MIP (Coupled Carbon Cycle Climate MIP), DAMIP (Detection and Attribution MIP), DCPP (Decadal Climate Prediction Project), ScenarioMIP, HighResMIP (High Resolution MIP), as well as the ocean/sea-ice OMIP simulations.

“…Ocean state estimates (e.g. Wunsch and Heimbach, 2013) effectively use heat content changes and air-sea fluxes to derive a time varying ocean circulation that maintains heat balance within errors for every ocean region. This is the inverse problem: use the principle of heat conservation along with the time history of heat content from Argo profiles and air-sea fluxes to derive the time-varying circulation that is necessary to conserve heat.…”

Abstract. The Atlantic meridional overturning circulation comprises warm upper waters flowing northward, becoming colder and denser until they form deep water in the Labrador and Nordic Seas that then returns southward through the North and South Atlantic. The ocean heat transport associated with this circulation is 1.3 PW, accounting for 25 % of the maximum combined atmosphere-ocean heat transport necessary to balance the Earth's radiation budget. We have been monitoring the circulation at 25
