MODIS / Terra NASA L2gen NIR Ocean Color Products (Backup)

The MODIS/Terra ocean color products are our backup products since the sensor has serious calibration problems. The 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 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.
