Well that leaves me utterly perplexed because I can't reproduce it with the 1 
degree GFS grib2 files. I'm curious if the avn file is actually grib1 and not 
grib2, since it didn't come through on your email before, would you please 
upload it to 

http://motherlode.ucar.edu/repository/alias/gempakuploads/

I will then be able to check it. 

Or, if you have a direct URL so I can wget the same file as you, that will 
work.  

Michael
