Abstract
	Derived ocean color products calculated from the MODIS sensor. Products are calculated from Remote Sensing Reflectance (Rrs) and/or top of atmosphere reflectance corrected for Rayleigh scattering and molecular absorption (Rhos).

Purpose
	For use in estimating water quality and detecting algal blooms in the Continental US.
