.ctl for MODIS HDF file

[Hao He]

Hi,
   I want to read MODIS HDF file by GrADS. Unfortunately both sdfopen and
xdfopen do not work for me, so I need to write a complete .ctl file. But
I am confused after reading the MODIS data set
(http://modis-atmos.gsfc.nasa.gov/MOD07_L2/format.html)
I am wondering if anyone has experience on it.
Thanks a lot!

Hao
