OSNAP data products will match those of the RAPID/MOCHA program, namely, time series of the depth and zonally-integrated volume, heat and freshwater fluxes. The ability of the observational data to accurately estimate these products has been tested in a series of Observing System Simulation Experiments (OSSEs) that, along with the calculation methodology, are detailed in the OSNAP technical report. The reader is also referred to the JTECH paper for details on the OSNAP calculation methods.
