Downwelling Spectral Irradiance (SPECTIR)

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, nominally 10 or 20 nm in width.
