At present, for different wind input files, different headers are used, which are read in different ways in the sourcecode. Some effort has been put in making the files more self-descriptive, readible and to make the input of the different files more consistent. For three four wind-input options, a suggestion to standardise the headers is shown below. The suggestion is conform a possible transition to NetCDF format in the future. See NetCDF standard names for more information on the used standard NetCDF names. For Space Varying Wind and Pressure, Pseudo ArcInfo wind, wind on a separate curvi-linear grid and Spiderweb wind, three examples of input files are shown below.
