Détection d'algues sargasses flottantes avec les satellites Sentinel-3A&B et AQUA (moyenne 7 jours)
Cartes combinées de l'indice de détection des sargasses NFAI (Normalized Floating Algae Index).
Produit grillé quotidien disponible en temps différé de février 2022 à mois - 1, dans le cadre du projet SCO SeSaM (www . spaceclimateobservatory . org/sesam) . Chaque carte représente la présence de sargasses (au travers d'un indice de détection d'algues flottantes normalisé) des 7 derniers jours à 0.01° de résolution.
