Description

add the a shapiro filtering of slopes, as done for the standard iso-neutral operator. It will be implemented under a logical

Implementation

Griffies triads slopes smoothing:

-add ln_smooth_triad logical in namtra_ldf.

-add ldf_slp_smooth subroutine to make the shapiro filtering for standard and triad operators.

-add calls to shapiro filtering in ldf_slp_triad.

-replace the shapiro filtering in ldf_slp (standard operator) by calls to ldf_slp_smooth subroutine.

Also add top condition for under ice shelf seas

  • for slopes computing
  • for diffusion computing

Tests

Triad operator is not activated in standard configurations

Replacing the shapiro filtering in ldf_slp (standard operator) by calls to ldf_slp_smooth subroutine has no impact: results are the same. ( tested)

To see differences, triads with smoothing must be activated. See plots with ORCA2 in ticket #2601

Sette tests are OK.
