Shen,

i created the table and attached. you can update the grib jar file using
the jar command at
http://java.sun.com/j2se/1.4.2/docs/tooldocs/solaris/jar.html

you have to update 2 files, tablelookup.lst fnmoc_3.tab

i didn't have a file to test with, so let me know if there's problems.
also, the url you sent me had multiple entries for some single parameters,
ie number 7. when i created the table i used the last one in the series
because this is the latest FNMOC table. hope that makes sense.
