John,
I use your template to open the file. But it is not right. Please have a
look at my .ctl file.
dset ^EMIS_CHINA_D1.ncf
title INTEX-B SO2 emission
undef -9999
pdef 94 67 lcc 34.8 113.7 1 1 30.0 60.0 113.7 30000 30000
xdef 94 linear 95.769 0.3659
ydef 67 linear 24.828 0.2644
tdef 25 linear 00:00Z03APR2008 1HR
zdef 34 linear 1 1
dtype netcdf
vars 1
SO2=>so2 0 t,z,y,x Sulfur Dioxide
endvars
