plotting error

[Kanawade, V.P.]

Dear All,

I am running GrADS on Windows vista. I am trying to plot 5 deg. gridded CO data at 150hPa level. I have created binary file (attached) and ctl file (attached). I am able to open ctl file but when try to plot data it gives me erro. I am unable to figure out whether there is problem with binary file or running GrADS on windows.

Any suggestion in this regard would be much appreciated. thank you in adv.

Please see below for error message -
