I somewhat randomly found some VIIRS OC files from 2012 with pversion QL. This is not an exhaustive list, just the granules over (47N -148E, 57N -123E). However, the input ozone and met files are not climatology.

There were some level-0 files on our archive from 2012 that were replaced with better copies when the format was changed, and the new L1A files were automatically submitted for  both QL and refined processing simultaneously.  Since the refined ancillary data from 2012 were available, both streams used the refined ancillary but it created a race condition where depending on the order of completion a 'refined' file was unintentionally overwritten by a 'QL'-labeled file. The only difference in these files is the 'QL' internal version.  I'll reprocess them so the the version label is consistent.

Thanks,
