Abstract

The dataset contains satellite-derived sea-surface ocean color (chlorophyll-a) measurements collected by means of the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor onboard the NASA Aqua satellite. The data is available at daily (2015 - present), weekly (2002 - present) and monthly (2002 - present) intervals at a spatial resolution of 0.05 degrees. The geographic coverage is global.
