Fan, I did a little more digging, and I don't think the file name extension will matter - that was my misinterpretation of how the table was getting picked up. However, you will probably have the best result directly embedding the table information in your featureCollection element using the xml notation. It looks like you tried this already, so I am not sure why it did not work for you. It is possible that it broke because you did not follow udunits standard -- for instance, square meters is notated as m^2, rather than m(superscript)2. The code you are asking about is just the number that identifies the grib parameter. Inside your <featureCollection> element: <gribConfig> <parameterMap> <parameter code="2"> <<-- This will override the standard table values for parameter 2 (code < 128 are standard, > 128 are local) <description>Pressure reduced to MSL</description> <units>Pa</units> <name>PRMSL</name> </parameter> <parameter code="131"> <description>Snowfall rate</description> <units>kg/m^2.s</units> <<--Compound units are notated with a dot, so /m^2/s is just /m^2.s <name>Snof</name> </parameter> ... </parameterMap> </gribConfig> -Lansing Madry Unidata Boulder, Colorado Ticket Details =================== Ticket ID: GJF-200148 Department: Support THREDDS Priority: Low Status: Closed
