WebAug 20, 2008 · The diffuse attenuation coefficient for downwelling irradiance (K d(λ)) is an important parameter for ocean studies. Based on the optical profile data measured during three cruises in the northern South China Sea in autumn from 2003 to 2005, variations in the K d(λ) spectra were analyzed. The variability of K d(λ) shows much distinct features in … WebUncertainty in global downwelling plane irradiance estimates from sintered polytetrafluoroethylene plaque radiance measurements Alexandre Castagna, B.
