Hello,
I am trying to read JMA forecast files in GRIB format with NCL.
The number of longitudinal grids reduced toward the poles
thus grids are not rectilinear.
These files do not follow NCL's convection and
does not provide gridx and gridy.
Longitude grid arrays are problematic as below.
Is there anything I can do in the script?
Otherwise I will preprocess the files with other tools.
