Ocean Color Data at the NASA GES DISC
The NASA GES DISC provides Giovanni visualization and analysis capabilities for data from the NASA SeaWiFS and MODIS-Aqua missions, including 8-day temporal resolution data products. In addition, Giovanni provides access to the NASA Ocean Biogeochemistry Model (NOBM) daily and monthly data. In the Water Quality data portal, both standard and evaluation NASA data products are available, and this portal will also host advanced chlorophyll a, euphotic depth, and total suspended sediments data at high spatial resolution for selected areas.
