Journal ArticleDOI
A model for the diffuse attenuation coefficient of downwelling irradiance
TL;DR: In this article, a semianalytical model for downwelling irradiance (Kd) is developed based on the radiative transfer equation, with values of the model parameters derived from Hydrolight simulations using the averaged particle phase function.
Journal ArticleDOI
Secchi disk depth: A new theory and mechanistic model for underwater visibility
Zhongping Lee,Shaoling Shang,Chuanmin Hu,Keping Du,Alan Weidemann,Weilin Hou,Junfang Lin,Gong Lin +7 more
TL;DR: In this article, the authors show that the Secchi disk depth (Z SD) may not exactly represent the sighting of a Secchi disc by a human eye. And they develop a new theoretical model to interpret Z SD, which relies only on the diffuse attenuation coefficient at a wavelength corresponding to the maximum transparency.
Journal ArticleDOI
Penetration of UV-visible solar radiation in the global oceans: Insights from ocean color remote sensing
Zhongping Lee,Chuanmin Hu,Shaoling Shang,Keping Du,Marlon R. Lewis,Robert Arnone,Robert J. W. Brewin +6 more
TL;DR: In this paper, the authors used the JPSS VIIRS-V1 satellite to study the effect of solar radiation on the Earth's magnetic field on the performance of the Earth satellite.
Journal ArticleDOI
Penetration of solar radiation in the upper ocean: A numerical model for oceanic and coastal waters
TL;DR: In this paper, the vertical transmittance of ESR is separated into two exponential terms, with one for the contributions of wavelengths below 700 nm (the visible domain, EVIS) and one for wavelengths above 700 nm(the infrared domain, EIR).
Journal ArticleDOI
An inherent-optical-property-centered approach to correct the angular effects in water-leaving radiance
Zhongping Lee,Keping Du,Kenneth J. Voss,Giuseppe Zibordi,Bertrand Lubac,Robert Arnone,Alan Weidemann +6 more
TL;DR: This IOP-centered system can be used to derive IOPs from angular Rrs and offers an alternative to the system centered on the concentration of chlorophyll and is applicable to oceanic and coastal waters as well as to multiband and hyperspectral sensors.
