[ncl-talk] read a variable name has space from hdf file

[Yun Yue]

Hi Mr. Shea,

Thanks very much, this solved my question. At the beginning I just used hdfview to see the hdf_name. When I used ncl_filedump I found there is a "_"  in the variable name.

Thanks very much,

Yun

Please use ncl_fildump to provide a view of how NCL 'sees' the file.

ncl_filedump ...MODIS...hdf | less

If it is a HDF-EOS file, just add a .he2 on the command line.

ncl_filedump ...MODIS...hdf.he2 | less

========
Do you see any variable names with a space? Likely not. NCL applies an underscore.

If you can not figure out the issue send the file tp

ftp ftp.cgd.ucar.edu<http://ftp.cgd.ucar.edu>
anonymous
email
cd incoming
put ...MIDIS_FILE...
quit

Then send the name of the file because we can not look a ./tp/incoming

Cheers

Hi NCL users,
I was using NCL to read MODIS Level 2 land data. The file format is hdf. I used the following NCL code to read a variable has space

f = addfile(filename,"r")
x = f->$"fire mask"$
The error is variable is not in file (f)

There's no error when I read other variables without space.
Does anyone know how to fix this? I appreciate any help.
Thanks,
Yun
