MODIS / Aqua NASA L2gen NIR Ocean Color Products

The MODIS/Terra ocean color products are derived by using the NASA L2gen SeaDAS codes based on Near-Infrared (NIR) atmospheric correction algorithm. The products include chlorophyll concentration and remote sensing reflectance at 667 nm over 2 CoastWatch Regions-of-Interest, i.e., Gulf of Mexico (GOM) and Hawaii (HI).

Remote sensing reflectances (Rrs 665, 667 or 670 nm) provide a proxy for the suspended sediments in surface waters. The Rrs anomaly is generated when today's data is compared to the bi-monthly mean. Bi-monthly mean values are averages calculated over 61 days.
