C Purpose: |
| 5 |
|
|
C To interpolate an arbitrary quantity from the 'dynamics' |
| 6 |
|
|
C grid to the higher resolution plumes grid |
| 7 |
|
|
C Algorithm: |
| 8 |
|
|
C Routine performs a direct copy of the field into all the |
| 9 |
|
|
C values on the higher resolution grid. |
| 10 |
|
|
C Dynamics -> Plumes retains the dynamics layer mean value. |

C Input: |
| 13 |
|
|
C qdyn1.... [im,jm,lmdyn,bi,bj] Arbitrary Quantity on Input Grid |
| 14 |
|
|
C qdyn2.... [im,jm,lmdyn,bi,bj] Arbitrary Quantity on Input Grid |
| 15 |
|
|
C idim1,2.. Limits for Longitude Dimension of Input |
| 16 |
|
|
C jdim1,2.. Limits for Latitude Dimension of Input |
| 17 |
|
|
C Lmdyn.... Vertical Dimension of Input |
| 18 |
|
|
C Nsx...... Number of processes in x-direction |
| 19 |
|
|
C Nsy...... Number of processes in y-direction |
| 20 |
|
|
C bi....... Index of process number in x-direction |
| 21 |
|
|
C bj....... Index of process number in x-direction |
| 22 |
|
|
C flag .... Flag to indicate winds (1) or temperature (0) interpolation |
| 23 |
|
|
C imout.... Number of points in x-direction to calculate |
| 24 |
|
|
C Lmout.... Vertical Dimension of Output |
| 25 |
|
|
C |
| 26 |
|
|
C Output: |
| 27 |
|
|
C qplume... [idim2,jdim2,im,Lmout] Quantity at output grid (plumes grid) |
| 28 |
|
|
C |
| 29 |
|
|
C Notes: |
| 30 |
|
|
C 1) This algorithm assumes that the output (plumes) grid boxes |
| 31 |
|
|
C fit exactly into the input (dynamics) grid boxes |
| 32 |
|
|
C 2) CAUTION! This routine, as currently written, assumes Lmdyn=Lmout |
