[ncl-talk] problem for map plotting data without explicit coordinate arrays

[Dave Allured - NOAA Affiliate]

All data publishers, please note.  This is why modern conventions like CF,
COARDS, etc. advocate for including complete coordinate arrays within
individual data files.

Lijun, you may get most accurate results if you go back to your data
source, and request or search for lat and lon coordinate arrays.
