CITATION: Jonasz M. 2007. Absorption coefficient of water: Data sources (www.tpdsci.com/Tpc/AbsCfOfWaterDat.php). In: Top. Part. Disp. Sci. (www.tpdsci.com). DATA: Smith R. C., Baker K. S. 1981. Optical properties of the clearest natural waters (200-800 nm). Appl. Opt. 20, 177-184. NOTES: The absorption coefficient values have been derived by the data authors by analysing selected existing data on the diffuse attenuation coefficient of the clearest ocean waters. Data have been rescaled by Jonasz M. to wavelength in µm. Each column is separated by a TAB - when you import the file into a spreadsheet all column headings should be aligned with the numbers.
