True color images look similar to a “photograph” of the earth and lakes from a space-borne satellite perspective. The Great Lakes CoastWatch node hosts satellite images from the following instruments:

  • Suomi National Polar-Orbiting Partnership spacecraft (VIIRS S-NPP)
  • NOAA-20’s Visible Infrared Imaging Radiometer Suite sensor (VIIRS NOAA-20)
  • Moderate-Resolution Imaging Spectroradiometer (MODIS) on-board the NASA Earth Observing System (EOS) Aqua and Terra satellite
  • European Sentinel 3-a Ocean and Land Colour Instrument (OLCI).
