I believe the palette files are just a list of colors upon which the range of data values are mapped. They don't specify how fill or missing values are displayed. Instead, by specify missing and fill values and maybe the valid range, you can change how the code determines the range of data values. This can be done in a few ways. First, if your data is stored in netCDF files (and you can modify your data files), you can set some combination of "missing_value", "_FillValue", "valid_min", and "valid_max" attributes. If your data is not netCDF or you can't modify them, you can add this information in the TDS configuration catalogs. Here's the netCDF page that describes these attributes: http://www.unidata.ucar.edu/software/netcdf/docs/netcdf/Attribute-Conventions.html Here's a TDS page on using NcML in the TDS configuration files: http://www.unidata.ucar.edu/projects/THREDDS/tech/tutorial/NcML.htm Let us know if you have any more questions.
