| 11 | !! *** routine dia_wri *** |
|---|
| 12 | !! |
|---|
| 13 | !! ** Purpose : output dynamics and tracer fields on direct access file |
|---|
| 14 | !! suitable for MPP computing |
|---|
| 15 | !! |
|---|
| 16 | !! ** define key : 'key_dimgout' |
|---|
| 17 | !! |
|---|
| 18 | !! ** Method : Default is to cumulate the values over the interval between |
|---|
| 19 | !! 2 output, and each nwrite time-steps the mean value is computed |
|---|
| 20 | !! and written to the direct access file. |
|---|
| 21 | !! If 'key_diainstant' is defined, no mean values are computed and the |
|---|
| 22 | !! instantaneous fields are dump. |
|---|
| 23 | !! Each processor creates its own file with its local data |
|---|
| 24 | !! Merging all the files is performed off line by a dedicated program |
|---|
| 25 | !! |
|---|
| 26 | !! ** Arguments : |
|---|
| 27 | !! kt : time-step number |
|---|
| 28 | !! kindinc : error condition indicator : >=0 : OK, < 0 : error. |
|---|
| 29 | !! |
|---|
| 30 | !! ** Naming convention for files |
|---|
| 31 | !! |
|---|
| 32 | !! {cexper}_{var}_y----m--d--.dimg |
|---|
| 33 | !! cexper is the name of the experience, given in the namelist |
|---|
| 34 | !! var can be either U, V, T, S, KZ, SSH, ... |
|---|
| 35 | !! var can also be 2D, which means that each level of the file is a 2D field as described below |
|---|
| 36 | !! y----m--d-- is the date at the time of the dump |
|---|
| 37 | !! For mpp output, each processor dumps its own memory, on appropriate record range |
|---|
| 38 | !! (direct access : for level jk of a klev field on proc narea irec = 1+ klev*(narea -1) + jk ) |
