[ncarg-talk] [6.4.0 version] Bug : Categorical Snow always null

[Sébastien POITEVIN]

Hi all,

When we read "Categorical Snow" with NCL 6.4.0 version (ncl_filedump -v
CSNOW_GDS0_SFC 20122017_15.grb or with 'PrintMinMax' command), we have
always null value (min and max value = 0)  whereas we have no problem when
we read the same grib file with the 6.3.0 version (min = 0 and max = 1).

Grib files are produced by WRF-NMM (version V3.7.1) and UPPV3.0.

Our system is "3.16.0-4-amd64 #1 SMP Debian 3.16.43-2+deb8u5 (2017-09-19)
x86_64 GNU/Linux"

Unfortunately I cannot send you a WRF grib file because it is too large.

Thanks for your help.
