#2690 closed Defect (fixed)

Sign convention of the isf freshwater fluxes

Description

Context

Point 2 of #2669: The freshwater flux (qfwf or fwfisf) is negative when melting. It does not really follow the nemo general rule of having positive runoffs.

Analysis

...

Recommendation

  • change sign through out the code to have flux from isf to oce and not the other way around
  • check impact on isf input file

Test : it should not change the results (run.stat) and should not change the WED025 output except for the sign

Comments on the sette results:

  • AGRIF failed as in the the trunk and results are the same between my branch and my reference trunk version => not an issue with my branch
  • SWG is not run and tested as in my reference trunk version => not an issue with my branch
  • all other results are positive
