VIIRS JPSS-1 filtering of QLP, QL and RF products

In fact my general needs are to download only new or updated files comparing to my local archive.After reading of several posts about NRT mirroring maybe I see another solution: I can ask with file_search for the files processed the last days using psdate and use the returned checksum or cdate to de...

Hi,We try to download on-the-fly new VIIRS JPSS-1 QLP, QL and RF products (and differentiate them), is there any way to know from an option of the query on-line command file_search if a product is QL or QLP or RF?For VIIRS SNPP we set up a non-extracted subscription to the QL data to get only QL wit...

Thanks in advance,

MODIS-Aqua QL subscription gives QLP

Thanks Sean for the explanations,

For this granule I compared the chlor_a of the 2 versions of 2018.0 (9.3.0-V2019.0 vs 9.2.0-V2017.0.3) and found that the values are not exactly the same. Is it normal? Are the 2 versions scientifically equivalent?

Regards,
Julien
