[ncl-talk] problem regrid WRF outputs to rectilinear grids using rcm2rgrid

[LSL]

Dear NCL community,


I am trying to regrid WRF outputs (Lambert Conformal Projection, 3km) to 
rectilinear grids (lat/lon, 0.5 degree) using rcm2rgrid.


It is found that the boundary of converted rectilinear grids are not 
exactly aligned with the black square lat/lon frame. As shown in the 
figure attached, they are a little drifted northward and eastward.


Anyone can tell me where is the problem? The script is also attached.
