Hi,

Thanks for providing the file offline.

I tried various things on it, including dumping the NO2Day variable with HDF's "h5dump" utility:

h5dump -d "/HDFEOS/ZAS/HIRDLS/Data Fields/NO2Day" --noindex *he5

This program does seem to show that there are some values in the file other than zeros and missing values.

I've created a ticket for this, NCL-1237. We'll let you know when we have more information on it.
