Florida-Georgia Coast Satellite Data
Data Descriptions and Download Links
Surface water temperature for Florida-Georgia Coast from NOAA's Advanced Very High Resolution Radiometer (AVHRR). Overpasses from all operating AVHRR instruments are averaged into a single daily, 3-day, or 7-day composite (composite includes day and night overpasses).

Sediment Index (Remote Sensing Reflectance at red wavelengths)
The remote sensing reflectance (Rrs) in the red wavelengths can be used as a surrogate for sediment concentration in the surface water. As the sediment load in the surface water increases, the reflectance in the red wavelengths will increase. Since the Rrs values are reflectance measurements and not sediment concentration measurements, only relative amounts of sediment in the water may be inferred. Higher Rrs values indicate relatively more suspended sediment compared to lower Rrs values. Patterns of suspended sediment distribution, both spatial and temporal, and sediment gradients may be detected and monitored.

Diffuse Attenuation Coefficient at 490 nm
Diffuse Attenuation Coefficient at 490 nm (Kd-490) from MODIS measures how strongly light intensity at the specified wavelength (490 nm) is attenuated within the water column. The "KD2" standard algorithm from NASA's Ocean Biology Processing Group is used, and processed operationally by NOAA CoastWatch. More information and data processing caveats.
