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: http://wwwt.emc.ncep.noaa.gov/gmb/STATS/tpb97/TPB02/html/v3.html Hope this helps Declan ----- Original Message ----- From: "Tom Grzelak" <address@hidden> To: <address@hidden> Sent: Tuesday, April 08, 2003 7:31 PM Subject: IS IT THE AVN OR GFS OR MRF OR ....? > > I have a question that I hope to gain consensus on.
