Hi Liu Zhong,
How are you? I guess you come from China, me too. I am in Canada now. I am
also using GrADS now and hope to learn how use it. Could you give me some
of your .ctl files and data files too, including the Fortran code used to
write the data file that is used as an input data to GrADS to me, so that
I can use them to have a test to my GrADS. I am curious about where you
are you, your status etc. Thanks!
Hope to hear from you.
