【Abstract】 An underwater spectroradiometer are designed to measure the apparent optical properties of of the upper water column. This new instrument can measure downwelling and upwelling irradiance at twelve wavelengths and upwelling radiance at seven wavelengths simultaneously. The center wavelength and bandwidth of each channel is compatible to that of remote sensors such as SeaWiFS. The new instrument’s design criteria, radiometric characteristics and field experimental data are described.更多还原
