Sea surface temperature and chlorophyll-a concentration were obtained from the MODerate-resolution Imaging Spectrometers (MODIS) aboard the both Terra and Aqua satellites obtained from OceanColor Web (http://oceancolor.gsfc.nasa.gov/) (Feldman & McClian, 2014). Terra was launched on December 1999 and the Aqua was launched on May 2002. Terra is set to be orbiting the Earth in the morning from north to south over the equator. Conversely, Aqua orbits the Earth from south to north across the equator in the afternoon. Terra and Aqua takes about one to two days for viewing the entire Earth’s surface, acquiring multidisciplinary data in 36 spectral bands, or wavelengths or groups (National Aeronautics and Space Administration, 2014).
