Hi, Roy!
Have you tried h4tonccf [1] or OPeNDAP Hyrax hdf4_handler [2] on your product?
May I download and look at your data product so that I can test with our
tools as well?
We'd like to help you if your HDF4 product cannot be converted to or served
as NetCDF successfully.

Subject: [thredds] Irregular grids
Hi All:
I am dealing with some L3 binned data, in what I will call the "Seawifs
format". The data is stored in an HDF file as a VData - basically one long
array or table if you want. The reason it is done this way is the "grid" is
irregular, that is each row has a varying number of columns. I can read the
data fine in python, but I am trying to find out what options I have for
serving it. Clearly one option is to grid the data at a somewhat coarser
resolution, and i might do that. But my questions are:
1. Is there a standard way to write this to a netcdf file (I can calculate
the lat-lon at the center of each bin)?
2. Can such a file be served by thredds, and if so what would it take.
3. If it can be served by thredds, does what gets returned make sense to
someone not familiar with what is going on (basically we deal with
unsophisticated users, it must be real clear what is being returned to them).
Thanks for any help.
-Roy M.
