Estimation of atmospheric turbidity from the burned traces of the Campbell-Stokes sunshine recorder.
A method is proposed to determine the atmospheric turbidity factor from records of sunshine autographs. These records have been available for half a century. The proposed method is applied to data from Denmark and compared with electrical conductivities in ice cores of Greenland and Lamb's dust veil index; both are measures of past volcanism.
