I see the same problem withe the "A1" grid identifier in the TTAAII for certain MRF-alikes, and suggest you contact the NWS data management technical contact: http://weather.gov/noaaport/html/contacts.shtml email: address@hidden Steve Chiswell Unidata User Support >From: "Christian =?ISO-8859-1?Q?Pag=E9?=" <address@hidden> >Organization: UCAR/Unidata >Keywords: 200410131401.i9DE1JNW029717 >Institution: UQAM >Package Version: LDM 6 >Operating System: IRIX64 >Hardware Information: SGI >Inquiry: Why since sept. 29th, the MRF-alike global GFS grids have improper WM > O headers? All the MRF-alike GFS grids now come with the headers from the gri > d #201 (the third letter being a A). The CONUS headers are no longer, and the > y come with an A instead of the I.
