Sigmet Raw Product files

Hi folks,

I need to view Sigmet Raw products in IDV.  These are Sigmet's
equivalent of Level II files.  I see two options:

1) Adapt the programs for reading WSR88D Level II files in
   /metapps/ucar/unidata/data/radar.

2) Convert the Sigmet files to NetCDF.  I see source code for
   reading radar data from NetCDF files in NetcdfRadarDataSource.java
   and NetcdfSweepfileAdapter.java, but I cannot find the format
   for the NetCDF files it reads (i.e. metadata, variable and
   dimension names, etc.).  Does anyone know where I can find this
   specification?  Output from ncdump on a sample file would be
   sufficient.

If I don't hear anything, I will proceed with option 1.  Stay tuned.

Thanks in advance,
