Description
While a clean field for the direct model has halos, wraparound and northfold properly filled (so that a lnc_lnk won't change a bit), a clean adjoint field has halos, wraparound and northfold zeroed (so that a lnc_lnk_adj won't change a bit).
As it is done now in adjoint tests, adjoint variables are set to 0 then initialized with loops over nl[de][ij]. So halos are indeed zeroed, but not wraparound nor northfold.
A solution would be to use tmaks_i, but then one also need u- and v- equivalents that do not exist (yet).
This only affect modules with a lbc_lnk_adj in it and does not seem to have a huge impact on test results (why bother :-()
Important note to NEMOTAM users: the above is true for any input of the adjoint (final condition or forcing), make sure their halos, wraparound and northfold are set to 0.
Attached are example of lbc_lnk_adj to different masks. From stupid (tmask) to what is done currently (nld_nle_loops) and what should be done (tmsk_i)
