The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA's Aqua satellite was launched on 4 May 2002.
It collects continuous multispectral radiometric data across 36 spectral bands, serving as a primary operational sensor for global ocean color, chlorophyll-a concentration, and sea surface temperature (SST) measurements.
SeaWiFS operated from 1997 to 2010.
Correct Option: Option 4 (AQUA-MODIS).
