These maps show the daily average number of bright sunshine hours across Australia for each month and the year. Sunshine hours are obtained from the Campbell-Stokes sunshine recorder, which uses a glass sphere to focus the sun's rays onto a calibrated paper card. When the sky is clear the focused rays burn a trace on the card, which is then used to determine the daily length of 'bright sunshine'.
