xWMB is a Python package that provides a efficient and lazy computation of Water Mass Budgets in arbitrary sub-domains of C-grid ocean models. Most of the heavy lifting is done by dependency packages by the same team of developers:
sectionate: for computing transports normal to a section (open or closed)regionate: for converting between gridded masks and the closed sections that bound themxbudget: for model-agnostic wrangling of multi-level tracer budgetsxwmt: for computing bulk water mass transformations from these budgets
Documentation is not yet available, but the core API is illustrated in the example notebooks here and in each of the dependency packages.
