[GrADS] How to plot stations climatology contour in a map?

[Qingfang Dai]

Dear Jayakrishnan,

Thanks so much for your great hints about oacres. I will try on this weekend and let you know the result.

Best,

Dai

Till now I am not familiarised with oacres. If you got the answer kindly let me know. But I know how to use oacres. refer grads documentation for details.
