[ecco-support] Global integral of vertical momentum flux not zero?

[Fabien Roquet]

Hello ECCO team,
I have downloaded ECCO from PO.DAAC.
Using WVELMASS from ECCO_L4_OCEAN_3D_VOLUME_FLUX_LLC0090GRID_DAILY_V4R4, multiplying with rA and summing along i, j, and tiles, I find the horizontal integral of w is not zero. Am I missing something?
See picture for the vertical profile of w, which is of order several Sv.
Thanks for your help,
Fabien
