황해 해역에서의 diffuse attenuation coefficient of down-welling irradiance에 대한 연구

Abstract

The diffuse attenuation coefficient for down-welling irradiance (Kd) is an important parameter for ocean studies including remote sensing applications. For the vast ocean, ocean color remote sensing is the only possible means to get the fine-scale measurements of Kd. To develop a technique of estimating Kd from remotely sensed data, the following underwater optical parameters (absorption coefficient (a), attenuation coefficient (c), scattering coefficient (b), diffuse attenuation coefficient (Kd), etc.) have been studied. For this research we conducted the field campaign around the Yellow Sea at 8~9 June, 2006. We obtained a set of underwater optical parameter data: down-welling irradiance (Ed), up-welling irradiance (Eu) and up-welling radiance (Lu) using TriOS optical sensors and a, c coefficient using Spectral Absorption and Attenuation Meter (AC-S). We then derived Kd values from Ed for each depth.
