HDF-SDS Read Error for dtype FLOAT32

[Zhong Liu]

Dear Henrique Barbosa,

I think you forgot to add the z dimension in the ctl file. Try to add z,
such as,

dset ^CSH.021001.6.HDF
dtype hdfsds
undef -9999.9
xdef 720 linear -180.0 0.5
ydef 148 linear -37.0 0.5
zdef 19 levels 0.5 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
tdef 1 linear 00Z01oct2002 1mon
vars 1
LatentHeating=>lh  19 t,z,x,y latent heat
endvars

Good luck.

Regards,

-Zhong
