New URL for NEMO forge! http://forge.nemo-ocean.eu

Since March 2022 along with NEMO 4.2 release, the code development moved to a self-hosted GitLab.
This present forge is now archived and remained online for history.

1004	!! - transform the received ocean stress vector from the received

1010	!! - oriented along geographical coordinate (if eastward-northward)

1012	!! - given at U- and V-point, resp. if received on 2 grids

1014	!! Therefore and if necessary, they are successively
