Estimation of downward irradiance attenuation from a single moored instrument
-A method for estimating the diffuse attenuation coefficient for downward irradiance, Kd(2), from time-series data of irradiance and sea-surface wave elevation is presented. Data acquisition is accomplished with a fixed-depth, single moored instrument system. K d (2) is obtained as a ratio of the standard deviation of natural logarithms of irradiance to the standard deviation of wave elevation....

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 کاملDiffuse 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 کاملThe vertical attenuation of irradiance as a function of the optical properties of the water
Average vertical attenuation coefficients, K(av), for irradiance calculated by linear regression of ln E(z) on z through the euphotic zone or from two irradiance values in a certain depth interval, are useful but somewhat arbitrary procedures for estimating these important apparent optical properties of the ocean. A more fundamental approach is to calculate an irradiance-weighted coefficient, K...
