[THREDDS #YXL-373395]: IndexOutOfBoundsException

Fan,

I think the problem is that the variable float ta is defined with dimensions 
[time plev lat lon].  Instead, the order on the dimensions should be reversed 
to [lon lat plev time].  If you try to open the file with the ToolsUI 
FeatureType->Grids, you get a nicer error that says no grids are found in the 
file.  Running the TDS in the debugger shows the same problem, but the TDS 
isn't giving a nice error message.

Thanks for bringing this to our attention!
