STRAYLIGHT flag on coastal areas
Hi,We found that the STRAYLIGHT flag logic on coastal areas is not the same for all sensors:- SeaWiFS: there is always a band of STRAYLIGHT pixels along the coastline (1 GAC or 3 MLAC pixels), and LAND pixels are always fully flagged STRAYLIGHT- VIIRSN/J1: the STRAYLIGHT on coastal areas follow the ...

SeaWiFS STRAYLIGHT GAC vs MLAC
Thanks Sean.If I'm not wrong other LAC sensors (MODIS/VIIRS) use simplified masking too?We observe that SeaWiFS MLAC are more contaminated by cloud borders than GAC and other LAC sensors, do you confirm this? So we are thinking to enlarge CLDICE+STRAYLIGHT for MLAC in our Level-3 processor. Do y...

SeaWiFS STRAYLIGHT GAC vs MLAC
Hi,Is it normal that the STRAYLIGHT flag for SeaWiFS is not consistent between GAC and MLAC products?For GAC it seems it is a simple fixed kernel around CLDICE but for MLAC it seems not the same algorithm.When removing CLDICE and STRAYLIGHT pixels, are MLAC products more contaminated by bad cloud bo...

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...

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

Select only day product with file_search tool?
Hi,
Is it possible to select only day product with the file_search tool? Like the Day/Night buttons on https://oceancolor.gsfc.nasa.gov/cgi/browse.pl?sen=am
Sorry if the answer is already in the forum but I did not found it.
Thanks in advance,
Julien

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

This cause rectangular holes on corr...
