Unfortunately, I'm not familiar enough with MM5 data formats to offer any
suggestions on how you might go about converting your MM5 data into a GRIB
format for use with MET.  We primarily deal with WRF data at the
Developmental Testbed Center (DTC).

However, by coincidence, on the same day we received your MET-Help
request, we received a help request from a different user who is using MM5
data.  He was able to convert it from sigma levels to pressure levels and
write out GRIB verison 1 files for use with MET.  I've written him to ask
for details on how he went about it.

I'll pass along any information or advice I hear from him to you.
