Maswood -- In the Data Choosers tab, open the "Data Source Type" list at the top of the panel and scroll down to "grids". Looking at your structure, you might need to make a couple of name changes (although I'm not sure anymore)....like "t" might need to be renamed "time" so the IDV recognizes that as time. I"m not sure about "z", but normally we use "altitude". Also your "y" and "x" should be renamed "lat" and "lon", and you probably need to add a "coordinate" attribute for the grids. Have a look at section 5.2 of the CF conventions: <http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.3/ch05s02.html> tom On Tue, Jul 29, 2008 at 10:19 AM, Maswood Hasan Mostafi <mostafi@xxxxxxxxx> wrote: > Hi Tom, > > Thanks for the quick reply.
