Water Temperature
AVHRR
Surface water temperature 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). Spatial resolution is
nominally 1 km.
GOES
Surface water temperature from NOAA's Geostationary Operational
Environmental Satellite (GOES) Imager instrument. Three-hourly
GOES snapshots are averaged into daily and 3-day composites
(composite includes day and night snapshots). Spatial resolution is
nominally 4 km.
Chlorophyll-a
MODIS
Chlorophyll-a from the Moderate Resolution Imaging Spectroradiometer (MODIS)
onboard the NASA Aqua satellite, processed using the NOAA OC3 algorithm with
the combined NIR-SWIR atmospheric correction (NOAA OC3 NIR-SWIR).

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. MODIS (Rrs at 667 nm)
VIIRS (Rrs at 672 nm)
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. True Color
True Color satellite image data from the Visible Infrared Imaging Radiometer Suite (VIIRS) at 750 m spatial resolution. Data files contain red, green and blue radiance data; images are also available. More information |
