Water Temperature

    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.

    Geo-Polar Blended
    Surface water temperature blended from all available U.S. and international geostationary and polar-orbiting satellites. Greater satellite orbit coverage and the blending technique assure these data are cloud-free. Only nighttime satellite overpasses are used. Spatial resolution is 5 km.

    PODAAC Multiscale Ultrahigh Resolution (MUR)
    Surface water temperature analysis from all available infrared and microwave satellites. Coverage from all satellites and the analysis method assure cloud-free coverage on a daily basis. Product is "foundational" SST, i.e. surface temperature before the diurnal heating begins. Spatial resolution is 1 km.

    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). More information

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.

    A high-resolution Kd-490 at 250m spatial resolution is also available from MODIS. The algorithm was developed by NOAA National Ocean Service, and is well-suited for coastal and turbid water.

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
