phycocyanin data

[mikewong]

Hello, I want to access satellite-observed bloom data for phycocyanin. I'm trying to follow the equation presented in Zhang et al. Environmental Health (2015) 14:41, which used pure water absorption at 665 and 709 nm. Could someone please advice me on acquiring this data from EarthData? If anyone knows of other methods, those are also welcomed. Much appreciated!
