C Purpose: |
| 5 |
C To interpolate an arbitrary quantity from higher resolution plume |
| 6 |
C grid to the model's dynamics grid |
| 7 |
C Algorithm: |
| 8 |
C Plumes -> Dynamics computes the plumes mean value, and in the case |
| 9 |
C of a vector field, preserves the direction of a vector |
| 10 |
C given in (uref,vref) |
| 11 |
C |
| 12 |
C Input: |
| 13 |
C qplume... [idim2,jdim2,im,Lmplume,bi] Quantity on Input Grid |
| 14 |
C idimin... Longitude Dimension of Input |
| 15 |
C Lmplume.. Vertical Dimension of Input |
| 16 |
C uref .... [im,jm,Lmout,bi,bj] Reference u-component of velocity |
| 17 |
C vref .... [im,jm,Lmout,bi,bj] Reference v-component of velocity |
| 18 |
C flag .... Flag to indicate vector (1) or scalar (0) interpolation |
| 19 |
C idim1,2.. Beginning and ending i-values of output grid |
| 20 |
C jdim1,2.. Beginning and ending j-values of output grid |
| 21 |
C Lmout.... Vertical Dimension of Output |
| 22 |
C Nsx...... Number of processes in x-direction |
| 23 |
C Nsy...... Number of processes in y-direction |
| 24 |
C bi....... Index of process number in x-direction |
| 25 |
C bj....... Index of process number in x-direction |
| 26 |
C |
| 27 |
C Output: |
| 28 |
C qdyn1..... [im,jm,Lmout,bi,bj] Field at output grid (dynamics) |
| 29 |
C qdyn2..... [im,jm,Lmout,bi,bj] Field at output grid (dynamics) |
| 30 |
C |
| 31 |
C Notes: |
| 32 |
C 1) Assume (for now) that the number of vertical levels is the |
| 33 |
C same on both the input and output grids |
