The problematic dataset is '/HDFEOS/SWATHS/O3NadirSwath/Data Fields/UTCTime'. This may be an h5py issue, I get the same error if I try to read the dataset in ipython.

Joe, can you create/find an example HDF5 file with vlen string and NULLTERM strpad?

[hyoklee]

Please ask HDF5 library team or help desk, not me.

[jreadey]

Doesn't look like a library issue. I've submitted an h5py issue: https://github.com/h5py/h5py/issues/565.

[hyoklee]

Thanks for submitting issue to h5py.
