Questions on NCL ESMF Regridding and Plotting

Dear NCL,

I have two issues with the NCL:

1) Regridding with ESMF
Has anyone here tested the NCL ESMF regridding function with real data,
actually I got problems when I did the regridding using Daymet data, what I
did was regridding 1KM to 3MIN and Half degree, and I found bias occurred
during the regridding using ESMF conserve method (which is not conserve,
the regridded output lost precipitation instead of conserve the value)

2)Plotting using the NCL 6.1.0
I got problems when plotting the half degree resolution and the 3MIN
resolution for the a same dataset(0.5 D was regridded from the 3MIN) , here
I show a figure which can
[image: Inline image 1]
[image: Inline image 2]
The first one is 0.5 degree and the following one is 3 MIN, however, I
expected to see some bricks(coarser grids) instead of so smoothing contour
in the half degree plot. Has anyone else has the same problem, or is there
a place to configure the plot setting to remove the smoothing effect?

Looking forward to hearing from you.

Best Regards,
