Sargassum Floating Algae Index Detection - GOES-16

Seagrass cover and composition Macroalgal canopy cover and composition Ocean colour

Maps of sargassum detection index NFAI (Normalized Floating Algae Index) using OLCI ocean color sensor onboard Sentinel-3A & Sentinel -3B satellites. Maps are delivered at 1km resolution in the Tropical Atlantic (included Gulf of Mexico) as instantaneous map acquired every 10 minutes (High resolution product) or on a daily basis averaging the 60 instantaneous maps (acquired every 10 minutes between 10:00 and 19:50 ITC). The variables available in the products are:

for dm dataset : fai_anomaly_daily_mean = floating algae index anomaly daily mean
for hr dataset : fai_anomaly = floating algae index anomaly
