For clarity, the phrase “heat storage rate” is used throughout the manuscript as shorthand for “rate of change of ocean heat storage.”
Because the ECCO state estimate is constrained by historical data, Fig. 1 should not be taken to represent a comparison to independent data; here, we mean simply to provide a context for ECCO heat transport values.
To be clear, our assessment of covariable heat transports does not constitute an assessment of eddy heat transports; in this solution, subgrid-scale eddy processes are parameterized and contained in the mixing terms, and thus are not contained in our heat transport decompositions; further analysis is needed to examine how the effects of parameterized subgrid-scale processes compare to higher-resolution solutions where eddies are permitted or resolved.
