 note = {application/pdf, In this study, the spectral transmittance of pure and impure sodium chloride water solutions, which is important for the thermal calculation of a solar pond, is measured for specimens of thicknesses of 1〜100 mm by means of an autorecording spectro-radiometer inside an air-conditioned room. Then, based on the spectral transmittance obtained here, the total transmittance of these pure and impure salty waters up to 3.2m deep is calculated as a ratio of the total radiation energy over all wavelengths arrived at any depth from the water surface of the solar pond to solar radiation incident upon the water surface with various air masses. According to the five-partition method extended from Nielsens’ four-partition method of wavelength, the absorption coefficient is calculated for each wavelength band. Finally, these transparent properties obtained for the pure and impure salty waters, i.e., the spectral and total transmittances, and the absorption coefficient for each wavelength band, are compiled as basic data for the use of solar energy by a solar pond.},
