Chlorophyll-a, Aqua MODIS, NPP, L3SMI, Global, 4km, Science Quality, 2003-present (Monthly Composite). Edited by Rachael Blake and Mary Hunsicker, accessed March 2017.

These data were accessed from https://coastwatch.pfeg.noaa.gov/erddap/griddap/erdMH1chlamday.html (MODIS) in March 2017. This dataset has Level 3, Standard Mapped Image, 4km, chlorophyll-a concentration data from NASA's Aqua Spacecraft. Measurements are gathered by the Moderate Resolution Imaging Spectroradiometer (MODIS) carried aboard the spacecraft. This is Science Quality data. This is the August 2015 version of this dataset.
