        Water Temperature
          AVHRR
          Surface water temperature from NOAA's Advanced Very High Resolution Radiometer (AVHRR). Overpasses from all operating AVHRR instruments are averaged into daily, 3-day, 7-day, monthly, seasonal and annual composites (composite includes day and night overpasses). Spatial resolution is nominally 1 km. More information
          AVHRR-VIIRS Multisensor
          Surface water temperature combined from the Advanced Very High Resolution Radiometer (AVHRR) and the Visible Infrared Imaging Radiometer Suite (VIIRS). Overpasses from all operating AVHRR and VIIRS instruments are averaged into daily, 3-day, 7-day, monthly, and seasonal composites (nighttime only). Spatial resolution is nominally 750 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). More information
          OLCI
          Chlorophyll-a from the Ocean and Land Colour Intrument (OLCI) onboard the European Sentinel-3A and 3B satellites, courtesy of the European Union's Copernicus satellite program. The data are processed with the European Space Agency's ocean color 4-band combination chlorophyll-a algorithm (OC4ME) and the MERIS 1999 Baseline Atmospheric Correction. More information
          VIIRS
          Chlorophyll-a from the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Suomi-NPP satellite, processed with the NOAA OC3 algorithm (Wang et al., 2017) and the NIR atmospheric correction of Jiang & Wang (2014). More information

        Diffuse Attenuation Coefficient at 490 nm

          Diffuse Attenuation Coefficient at 490 nm (Kd-490) measures how strongly light intensity at the specified wavelength (490 nm) is attenuated within the water column. It is a measure of the water's turbidity.

          MODIS (NASA "KD2" algorithm, 1 km)

          MODIS (NOAA/NESDIS algorithm, 1 km)

          OLCI (ESA M07 algorithm, 300 m)

          VIIRS (NOAA/NESDIS algorithm, 750 m)

        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)


        Total Suspended Matter

          Total suspended matter (TSM) is a measure of the concentration of particulate material in the surface water such as mud, silt, and other fine-scale debris, including both organic and inorganic fractions.

        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
