SPECIAL MESSAGE:

GOES-13 Sounder IR data is not available. All products from GOES-13 (GOES-East) Sounder IR data have been halted and distribution has been stopped except the Sounder ASOS SCP products for CONUS, which are replaced with GOES-East Imager ASOS SCP products for CONUS. Engineers are investigating the problem.

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).

Chlorophyll concentration provides an estimate of the live phytoplankton biomass in the surface layer. It is also referred to as the amount of the green pigment chlorophyll. The chlorophyll anomaly is generated when today's chlorophyll concentration data is compared to the bi-monthly mean. A positive anomaly indicates new algal growth. Bi-monthly mean values are averages calculated over 61 days.
