$
$ Define output data ------------------------------------------------- $
$
$ Define output server mode. This is used only in the parallel version
$ of the model. To keep the input file consistent, it is always needed.
$ IOSTYP = 1 is generally recommended. IOSTYP > 2 may be more efficient
$ for massively parallel computations. Only IOSTYP = 0 requires a true
$ parallel file system like GPFS.
$
$    IOSTYP = 0 : No data server processes, direct access output from
$                 each process (requirese true parallel file system).
$             1 : No data server process. All output for each type 
$                 performed by process that performes computations too.
$             2 : Last process is reserved for all output, and does no
$                 computing.
$             3 : Multiple dedicated output processes.
$

$
$ Five output types are available (see below). All output types share
$ a similar format for the first input line:
$ - first time in yyyymmdd hhmmss format, output interval (s), and 
$   last time in yyyymmdd hhmmss format (all integers).
$ Output is disabled by setting the output interval to 0.
$
$ Type 1 : Fields of mean wave parameters
$          Standard line and line with logical flags to activate output
$          fields as defined in section 2.4 of the manual. The logical
$          flags are not supplied if no output is requested. The logical
$          flags can be placed on multiple consecutive lines. However,
$          the total number and order of the logical flags is fixed.
$                               The raw data file is out_grd.ww3, 
$                               see w3iogo.ftn for additional doc.

$ Output request flags identifying fields as in ww3_shel input and
$ section 2.4 of the manual. If the first flag is 'N' then a namelist
$ is read. See ww3_ounf.inp for an example

$
$ Type 2 : Point output
$          Standard line and a number of lines identifying the 
$          longitude, latitude and name (C*10) of output points.
$          The list is closed by defining a point with the name
$          'STOPSTRING'. No point info read if no point output is
$          requested (i.e., no 'STOPSTRING' needed).
$          Example for spherical grid.
$                               The raw data file is out_pnt.ww3, 
$                               see w3iogo.ftn for additional doc.
$
$   NOTE : Spaces may be included in the name, but this is not
$          advised, because it will break the GrADS utility to 
$          plots spectra and source terms, and will make it more
$          diffucult to use point names in data files.

$ Homogeneous field data --------------------------------------------- $
$ Homogeneous fields can be defined by a list of lines containing an ID

$ convention degrees)) and air-sea temparature difference (degrees C).
$ 'STP' is mandatory stop string.
$ Also defined here are the speed with which the grid is moved
$ continuously, ID string 'MOV', parameters as for 'CUR'.
$
$  'LEV' 19680606 010000    1.00
$  'CUR' 19680606 073125    2.0    25.
