C !DESCRIPTION: |
| 15 |
C *==========================================================* |
| 16 |
C | S/R OBCS_COPY_TRACER |
| 17 |
C | Copy tracer value from the OB location to narrow band |
| 18 |
C | region (width = same as overlap) beyond the OB. |
| 19 |
C *==========================================================* |
| 20 |
C | Note: need this copy after an EXCH when: |
| 21 |
C | 1) a several grid-point stencil scheme (e.g., high order |
| 22 |
C | advection scheme) is used for tracer. |
| 23 |
C | 2) OB is so close to tile edge (e.g., OB_Iw=1) that, to |
| 24 |
C | compute fluxes at the OB, a high-order scheme will |
| 25 |
C | use grid points from the overlap region. |
