- comment :
- Model data on the 1x1 grid includes values in all cells for which any ocean exists on the native grid. For mapping purposes, we recommend using a land mask such as World Ocean Atlas to cover these areas of partial land. For calculating approximate integrals, we recommend multiplying by cell area (areacello).
