Using GrADS to open HDF-EOS

It's not clear which data you are looking at, level 2 or level 3.  The
descriptor file below I used to analyze the level 3 global 5km MODIS
LST product.  I don't think level 2 is possible.

When i've wanted to analyze the level 2 granules in grads, I had to
first convert to a regular grid. I think HDFView will do that, but not
in a batch way.

I hope that someone has a better answer than mine!
