C !DESCRIPTION: |
| 22 |
C Arguments: |
| 23 |
C |
| 24 |
C fName (string) :: base name for file to write |
| 25 |
C filePrec (integer) :: number of bits per word in file (32 or 64) |
| 26 |
C globalFile (logical):: selects between writing a global or tiled file |
| 27 |
C useCurrentDir(logic):: always write to the current directory (even if |
| 28 |
C "mdsioLocalDir" is set) |
| 29 |
C arrType (char(2)) :: declaration of "arr": either "RS" or "RL" |
| 30 |
C kSize (integer) :: size of third dimension: normally either 1 or Nr |
| 31 |
C kLo (integer) :: 1rst vertical level (of array "arr") to write |
| 32 |
C kHi (integer) :: last vertical level (of array "arr") to write |
| 33 |
C arr ( RS/RL ) :: array to write, arr(:,:,kSize,:,:) |
| 34 |
C irecord (integer) :: record number to write |
| 35 |
C myIter (integer) :: time step number |
| 36 |
C myThid (integer) :: thread identifier |
| 37 |
C |
| 38 |
C MDS_WRITE_FIELD creates either a file of the form "fName.data" and |
| 39 |
C "fName.meta" if the logical flag "globalFile" is set true. Otherwise |
| 40 |
C it creates MDS tiled files of the form "fName.xxx.yyy.data" and |
| 41 |
C "fName.xxx.yyy.meta". If jrecord > 0, a meta-file is created. |
| 42 |
C Currently, the meta-files are not read because it is difficult |
| 43 |
C to parse files in fortran. We should read meta information before |
| 44 |
C adding records to an existing multi-record file. |
| 45 |
C The precision of the file is decsribed by filePrec, set either |
| 46 |
C to floatPrec32 or floatPrec64. The precision or declaration of |
| 47 |
C the array argument must be consistently described by the char*(2) |
| 48 |
C string arrType, either "RS" or "RL". |
| 49 |
C (kSize,kLo,kHi) allows for both 2-D and 3-D arrays to be handled, with |
| 50 |
C the option to only write a sub-set of consecutive vertical levels (from |
| 51 |
C kLo to kHi); (kSize,kLo,kHi)=(1,1,1) implies a 2-D model field and |
| 52 |
C (kSize,kLo,kHi)=(Nr,1,Nr) implies a 3-D model field. |
| 53 |
C irecord=|jrecord| is the record number to be written and must be >= 1. |
| 54 |
C NOTE: It is currently assumed that the highest record number in the file |
| 55 |
C was the last record written. Nor is there a consistency check between the |
| 56 |
C routine arguments and file, i.e., if you write record 2 after record 4 |
| 57 |
C the meta information will record the number of records to be 2. This, |
| 58 |
C again, is because we have read the meta information. To be fixed. |
