Hi,
I don't know for certain, but I am curious about the actual values used in:
res@mpProjection = "LambertConformal"
res@mpLambertParallel1F = lat2d@mpLambertParallel1F
res@mpLambertParallel2F = lat2d@mpLambertParallel2F
res@mpLambertMeridianF = lat2d@mpLambertMeridianF
In particular, the first plot looks like the value for mpLambertMeridianF is something considerably to the west. What happens if you make it something like the center of your zoom window?
Hope that helps…
Rick
