Acknowledgement and References  Background and motivation Although VIIRS has been shown to provide consistent products to continue MODIS observations, the lack of a fluorescence band hinders its ability to detect and quantify harmful algae blooms (HABs) in waters rich in colored dissolved organic matter (CDOM). Nearly all Chla retrieval algorithms suffer in CDOM-rich waters, and this is why MODIS nFLH has been used to detect HABs (or red tides) in the eastern Gulf of Mexico (GOM).
