Attached is a simple script that reads/plot the hdf5  [HDF-EOS] file

If you are 'new' to NCL, please look at the excellent DKRZ manual:

*https://www.ncl.ucar.edu/Document/Manuals/NCL_User_Guide/NCL_User_Guide_v1.1_A4.pdf*
<https://www.ncl.ucar.edu/Document/Manuals/NCL_User_Guide/NCL_User_Guide_v1.1_A4.pdf>

There is no 'magic': all languages [computer and spoken] require the user
to spend time to learn.
