[ncl-talk] how to get the dimension size in netcdf file

[LeiTing]

Dave,Thank you so much. That is already the solution I need. However, can NCL be "smarter" that ,say, I can directly ask for the size of a named dimension?I know I can do it after using the function you pointed out, however, I'm just wondering if there are some tip that directly do it.Thanks a lot.Ting
