I may be spamming again..but we get GFS stratospheric data (7,5,3,2mb data) from the Climate Prediction Center. I received this notice from them on 26 Sept. This may explain some things: "...We provided you with 0.5x0.5 gridded fields from the GFS. Operations, today, changed this grid format to the native gaussian grid which is 1152x576..."
