In reviewing G02202 V6 data and comparing to v5, we found some differences that were larger than expected. On inspection, days with large differences were the result of those days being completely temporally filled - no source data was found for the day in question.
Reprocessing fixed these issues - the data was present, but we think that maybe CMR or something with earthaccess maybe caused us to treat a day as missing when data was actually expected.
We likely need to review the code responsible for determining if a granule for a date/hemisphere exists or not. Ideally we query CMR to see if the granule exists, and then download it. Missing granules should be clearly tracked somewhere so that we can flag unexpectedly missing days.
