Brian,

[I drove your email into our support-email tracking system so that we have 
permanent record that others can find. Hope you don't mind.]

The product is already trying to be decoded by the GRIB2-handling code, so an 
addition to the relevant GEMPAK GRIB2 table "g2varsncep1.tbl" should suffice to 
process this new product.
