OSNAP Model Truth Code (Python)
As part of an international effort, the Overturning in the Subpolar North Atlantic Program (OSNAP), is an ocean observing system that continuously measures trans-basin velocity, temperature and salinity of the full water column in the subpolar North Atlantic since 2014. As there is a broad interest in the community to compare model simulations with observational estimates, we provide a simple Python code that computes the meridional overturning circulation (MOC) from a model dataset interpolated onto the OSNAP section. Please note that this code is the beta version. We appreciate any feedback that could be useful for later versions. In addition, there are ongoing efforts to make this code generalized for any model dataset in future versions.
