Re: question about plot after regrid

It looks like you have requested "ManualLevels" but you didn't provide the
levels. I suspect NCL is then reverting to automatic levels selection which
is where the differences come from. If you change your code to specify the
levels with something like:

res@cnLevelSelectionMode = "ManualLevels"
res@cnMinLevelValF = 230
res@cnMaxLevelValF = 310
res@cnLevelSpacingF = 10

Then both panels should use the same colors.
