Abstract :
We discuss the validation activities of Ocean Color products Chlorophyll Concentration (Chlor_a) and water leaving radiances (nLw) using NPP-VIIRS data at NOAA CoastWatch. The current analysis is for the EDR products. Further, Level 4 products like the daily Chlorophyll Anomaly is used by operational users for Harmful Algal Bloom monitoring. CoastWatch´s role is to ensure that good quality VIIRS products comparable to heritage ocean color sensor products from MODIS and SeaWiFS are produced to meet the users´ data continuity needs.
