MODIS AQUA chla degradation since 2023 and its use?
Posted: Thu Mar 05, 2026 10:25 am America/New_York
Hello,
I would like to use timeseries of MODIS-Aqua ocean color data (Chl-a, SST, PAR, Kd490, PIC, POC) from 2002 up to, ideally, 2025.
Could you please advise if it is acceptable to use these data for research purposes since 2023, given the degradation notice of MODIS starting in 2023 (viewtopic.php?t=5333
)? I have noticed that some papers still use MODIS Chl-a time series up to 2024.
Alternatively, would it be better to collate VIIRS (SNPP_VIIRS) data after 2023?
Any guidance on how to handle this issue would be greatly appreciated.
Thank you very much for your help!
Best regards,
Andre
