Description

Downwelling Spectral Irradiance is the measure of electromagnetic radiation per unit area received (i.e. incident) by a sensor within the seawater column. Downwelling spectral irradiance is calculated from measurements made across 7 specific- pre-defined wavebands as follows: 1 = 412nm, 2 = 443nm, 3 = 490nm, 4 = 510nm, 5 = 555nm, 6 = 620nm, 7 = 683nm.
