Hi ,
I'm NCL beginner.
I need help .
data pediod : 212
lat : 121 (20N-90N, 0.5 interval) grids
lon : 241 (190-310, 0.5 interval ) grids
Data value for North America except ocean is non-missing.
I drew contour plot for 1st time.
But the figure using NCL was different from using Grads.
I use the following NCL script.
I want to draw exactly.
Help me~
Thank you ~
