Diffuse Attenuation Coefficient of Downwelling Irradiance: An Evaluation of Remote Sensing Methods
The propagation of downwelling irradiance at wavelength from surface to a depth (z) in the ocean is governed by the diffuse attenuation coefficient, ) ( d K . There are two standard methods for the derivation of ) ( d K in remote sensing, which both are based on empirical relationships involving the blue-to-green ratio of ocean color. Recently, a semianalytical method to derive ) ( d K from ref...
متن کاملA model for the diffuse attenuation coefficient of downwelling irradiance
[1] The diffuse attenuation coefficient for downwelling irradiance (Kd) is an important parameter for ocean studies. For the vast ocean the only feasible means to get fine-scale measurements of Kd is by ocean color remote sensing. At present, values of Kd from remote sensing are estimated using empirical algorithms. Such an approach is insufficient to provide an understanding regarding the vari...

متن کاملA model of diffuse attenuation of downwelling irradiance for ecosystem models
Estimation of the underwater attenuation of light is important to ecosystem modellers, who require information on Photosynthetically Available Radiation ( PAR ), and on the euphotic depth for calculation of primary production. Characterisation of these processes can be achieved by determining the diffuse attenuation coefficient of PAR , KPAR . A review of bio-optical models of the spectral diff...
متن کاملDetermination of the Downwelling Diffuse Attenuation Coefficient of Lake Water with the Sentinel-3A OLCI
The Ocean and Land Color Imager (OLCI) on the Sentinel-3A satellite, which was launched by the European Space Agency in 2016, is a new-generation water color sensor with a spatial resolution of 300 m and 21 bands in the range of 400–1020 nm. The OLCI is important to the expansion of remote sensing monitoring of inland waters using water color satellite data. In this study, we developed a dual b...
