Thanks Rick.<br>

I got the "best" smoothing using:<br>
<br>
; smoothing options<br>
res@cnSmoothingOn = True<br>
res@cnSmoothingDistanceF = .0001 ; best 0.0001<br>
res@cnSmoothingTensionF = 7.5 ; best 7.5.<br>
<br>
This is the result:<br>

"Best" rather subjective, but I tried to optimize the colour
transitions to reflect reasonable gradients. <br>
<br>
Much appreciated,<br>
