netCDF 4.0 group data read by NCL is different from ncdump

Dear all,

I am using NCL 6.1.2 to read netCDF 4.0 data within groups.
But the results are different from that I got using ncdump.

I uploaded the test file snd_LImon_all-mdl_historical_all-nsm_clm.nc onto
ftp.cgd.ucar.edu/incoming.

Here is my codes:
 dir = "~/data/cmip5/output/4plot/"
 fn = "snd_LImon_all-mdl_historical_
all-nsm_clm.nc"
 gg = "/snd_CCSM4/lat"
 dd = fin->$gg$
 print(dd)

The results will be all 0.
But using ncdump, I can get the valid latitude from -90 to 90.

Thank you!

Best,
Wenshan
