C !DESCRIPTION: |
| 20 |
C Arguments: |
| 21 |
C |
| 22 |
C fName (string) :: base name for file to read |
| 23 |
C filePrec (integer) :: number of bits per word in file (32 or 64) |
| 24 |
C useCurrentDir(logic):: always read from the current directory (even if |
| 25 |
C "mdsioLocalDir" is set) |
| 26 |
C arrType (char(2)) :: declaration of "arr": either "RS" or "RL" |
| 27 |
C kSize (integer) :: size of third dimension: normally either 1 or Nr |
| 28 |
C kLo (integer) :: 1rst vertical level (of array "arr") to read-in |
| 29 |
C kHi (integer) :: last vertical level (of array "arr") to read-in |
| 30 |
C arr ( RS/RL ) :: array to read into, arr(:,:,kSize,:,:) |
| 31 |
C irecord (integer) :: record number to read |
| 32 |
C myIter (integer) :: time step number |
| 33 |
C myThid (integer) :: thread identifier |
| 34 |
C |
| 35 |
C MDS_READ_FIELD first checks to see IF the file "fName" exists, then |
| 36 |
C IF the file "fName.data" exists and finally the tiled files of the |
| 37 |
C form "fName.xxx.yyy.data" exist. Currently, the meta-files are not |
| 38 |
C read because it is difficult to parse files in fortran. |
| 39 |
C The precision of the file is decsribed by filePrec, set either |
| 40 |
C to floatPrec32 or floatPrec64. The precision or declaration of |
| 41 |
C the array argument must be consistently described by the char*(2) |
| 42 |
C string arrType, either "RS" or "RL". |
| 43 |
C (kSize,kLo,kHi) allows for both 2-D and 3-D arrays to be handled, with |
| 44 |
C the option to only read and fill-in a sub-set of consecutive vertical |
| 45 |
C levels (from kLo to kHi) ; (kSize,kLo,kHi)=(1,1,1) implies a 2-D model |
| 46 |
C field and (kSize,kLo,kHi)=(Nr,1,Nr) implies a 3-D model field. |
| 47 |
C irecord is the record number to be read and must be >= 1. |
| 48 |
C The file data is stored in arr *but* the overlaps are *not* updated, |
| 49 |
C i.e., an exchange must be called. This is because the routine is |
| 50 |
C sometimes called from within a MASTER_THID region. |
