A note on the measurement of atmospheric turbidity

Rangarajan, S. (2011)

In a recent letter to the Editor, Tellus, Dr Ångström (1972) has raised some doubts about the accuracy of the values of the wavelength exponent ‘?’ obtained by me using photoelectric Sun photometers that operate at the wavelengths 0.40 and 0.60 micron.DOI: 10.1111/j.2153-3490.1973.tb00643.x
