Here is a chronology of sorts:

03/05/2002 : AVN runs four times a day out to 384 hours. Resolution is
T170L42 to 180h, thereafter T62L28.

04/23/2002 00Z: MRF is replaced by the 00Z AVN.

Sept-Oct 2002: Name changes: The AVN will be referred to as the Global
Forecast System model (GFS).

10/29/02 12Z: Resolution change
old: T170L42 to 180h, T62L28 to 384h
new: T254L64 to 84h, T170L42 to 180h, T126L28 to 384h

Also, see the following:

Hope this helps
Declan
