Displaying u and v wind data from two separate files

[Charles Williams]

Dear GrADS users,

I was wondering if anyone could help me with what is probably a very simple problem.  

I am trying to view vector wind data from two separate self describing NetCDF files (uwind.nc and vwind.nc corresponding to the two wind components) - ending up with an image showing wind direction (arrows) and wind strength (shaded contours).  How can I do this?  I really have 2 questions therefore: i) how can I have both files open at the same time such that both can be displayed at once; and ii) how can I use both vector and contour gxout options?

If it helps anyone to understand what I want to end up with, it is more or less exactly the same as the images produced from the daily composite online tools from the CDC.  The only reason I am downloading the NetCDF file and doing it myself is because I want to fiddle about with colours and intervals.

Many thanks,

Charlie Williams
