Anh Dao,
We only keep a few days of decoded data around, and not as far back as you are 
looking for.
You can find the 1 degree GFS data on the nomads.ncdc.noaa.gov for several 
years.
We have a needdata email list where you might find other sites in the community 
which have the data
you are looking for.

There are AMS conference presentations on the AODT which I found on the web 
such as:

   pdf of extended abstract: http://ams.confex.com/ams/pdfpapers/75410.pdf

NCEP's NAWIPS implementation is highlighted in the PPT presentation:
