Direct and indirect determination of the Linke turbidity …

NettetMeasures of turbidity refer to the total aerosol optical depth, either directly at a specified wavelength (e.g., the Volz turbidity factor or the Ängström turbidity coefficient, which is referenced to a wavelength of 1 μm), or indirectly by the ratio of aerosol to Rayleigh optical depth (e.g., the Linke turbidity factor). Nettetstrom's turbidity coefficient is calculated from spectral direct irradiance at two wavelengths, usually 380 and 500 nm, in a part of the solar spectrum where absorp tion is negligible. Up to now, Linke's turbidity factor TL has been less used than Angstrom's coefficient, although its experi mental determination seems to be easier. The main the wire roberto
