<DIV>Hi, everyone:</DIV>
<DIV> </DIV>
<DIV>I am trying to plot 500 hpa geopotential height. I used wrf_user_getvar to
get gh and wrf_user_intrp3d to interpolate to 500 hpa. Please verify I am doing
right. </DIV>
<DIV> </DIV>
<DIV>gh
= wrf_user_getvar(b,"geopotential",-1)</DIV>
<DIV>gh
= gh / 9.8 / 10.</DIV>
<DIV>; interpolation</DIV>
<DIV>gh_plane = wrf_user_intrp3d(gh, p, "h",
500, 0., False)</DIV>
<DIV> </DIV>
<DIV>For the contour lines, I noticed there are a bunch of small circles over
the Rocky Mountain as shown in the attached f1.png. What I want is a smoother
plot as in the black lines in f2.png. Those small gh line circles actually
coincide with the topograph as shown in f3.png. Please let me how I can plot a
smooth gh as in f2. </DIV>
<DIV> </DIV>
<DIV>thanks,</DIV>
