| 9 | • Works using a NEMO style namelist to initiate BDY configuration. |
| 10 | • Automatic identification of BDY points from a user chosen or predefined mask |
| 11 | • KDTree nearest neighbour matchup between the identified BDY points and the associated locations on source grid |
| 12 | • Data are first interpolated (horizontally) from source grid to destination BDY points using: |
| 13 | • Bi-linear |
| 14 | • Gauss-like – distance weighted function using nearest 9 points with a de-correlation distance r0 proportional to dx*cos(lat(j,i)) |
| 15 | • Nearest – takes closest point on distance (for use with similar res src and dst grids) |
| 16 | • Then in the vertical |
| 17 | • Linear |
| 18 | • Cubic-Spline |
| 19 | • Output in NEMO v3.2/3.3 and 3.4 forms |
| 20 | • Time stretching used to accommodate mismatch in source and destination calendars |
| 21 | • Optional smoothing of BDY boundary (post interpolation) |
| 22 | • Should be able to accept non NEMO netcdf src files, but not tested yet |
| 23 | • Handles rotation of vector quantities and can accommodate rotated grids (e.g. pan arctic) |
| 24 | • At present is only coded to use TPXO7.2 inverse tidal model to provide tidal boundary conditions |
| 25 | • Recently add a hack to setup generic tracer boundary conditions (e.g. so one can include nutrients for coupled ecosystem simulations |
