Re: Problems reading GRIB2 files

Gerry,

Thanks for your quick reply.

Sorry that I cannot access that computer until I am back to office tomorrow
(I am from Hong Kong).

As I remember, the path /data2/share/ncarg/lib/ncarg/ does exist but there
is no "grib2_codetables" folder inside. What does that codetable folder
essentially do?
