## Abstract The potential of Campbell‐Stokes records of sunshine hours has not been exploited. Since 1924 various forms of the Angstrom equation have been used to estimate mean daily global radiation from the mean daily fraction of possible ‘bright’ sunshine. the Angstrom equation gives an equal ra
