Chlorophyll-a, Aqua MODIS, NPP, 0.0125°, West US, EXPERIMENTAL, 2002-present (3 Day Composite)

Metadata Updated: September 9, 2022

NOAA CoastWatch distributes chlorophyll-a concentration data from NASA's Aqua Spacecraft. Measurements are gathered by the Moderate Resolution Imaging Spectroradiometer (MODIS) carried aboard the spacecraft. The algorithm currently used in processing the water leaving radiance to chlorophyll concentration has not yet been accepted as science quality. In addition, assumptions are made in the atmospheric correction in order to provide the data in a timely manner.
