Re: How to plot the topography in Y-Z plate?
Dear Shankar
Thanks for your scripts!
I generated a levitus_mask,and it works well.
I also generated a mask file with my model data, it also
works but the resolution is somewhat too coarse.
There is one more question.
Now, for example,I use
go fland_levitus z=1:5000 y=90s:90n
It gives me a topography. But, what's the longitude it uses as
the value of x?
I read the script but can not understand it well, but I guess
it used some default lon. Since I want the lon. average
topography, how to modify your script to do this?
Thanks a lot!
yours,
Kun
