NCT4 Ancillary Data Unpack
Posted: Fri Aug 19, 2011 3:00 pm
I am working to unpack and convert the NCT4 dataset to ADL input format to run the VIIRS Aerosol Algorithm. The SDRs, cloud mask, and geolocation were no problem but I have run into trouble using the ADL hdf unpacker on the NCT4 ancillary data (NCEP and NAAPS). I get the following error (same for NCEP and NAAPS fiiles):

I'm not sure what the problem is...!
