Thanks for your help. We didn't have any fields in gdinfo with ETAM (or EATM) as GVCOORD, but we did have PWTR for GLEV=0, GVC=NONE, and it worked. I'm not sure what changed a month ago, but our former method worked fine until then.
Again, I'll check with Steve when he returns to see if he knows of any changes in the ETA grids.
I looked over the alden http site and don't see any comparable forecast maps to the NGM ones (4 panels for 12,24,36,48 hrs). I don't even see more than a handful of Eta forecast products (individual field at maybe one time). Do you know offhand the numbers assigned to the Eta products - assuming the nice 4-panel charts exist? (Our NGM charts are the 2043-2047 series). I was at CSU on a visit last summer and it seemed to me that even they still had only the NGM maps, which re-inforced my idea that maybe those were the only model maps available (which seemed odd since the NGM was supposed to disappear this year.)
Sorry, I was confused. The 4-panel charts are indeed NGM and there are no ETA forecasts like that on the DIFAX circuit. I would imagine that when the NGM does go away, the charts will be replaced with ETA versions. Of course, you can always create your own ETA versions using GEMPAK. ;-) Don Murray
