c domain of a variable from an IVE-NetCDF file.
|
|
|
440 |
c Prior to calling this routine, the file must be opened with

441 |
c a call to opncdf (for extension) or crecdf (for creation) or
|
|
|
442 |
c readcdf (for readonly).

c time real input the user-supplied time-level of the
|
|
|
449 |
c data to be read from the file (the time-
|
|
|
450 |
c levels stored in the file can be obtained
|
