Mean monthly, seasonal and annual 9am and 3pm cloud grids, showing the cloud values across Australia in the form of two dimensional array data. The mean data are based on the standard 30-year period 1976-2005. Total cloud amount data is recorded at a network of weather stations across Australia. The total cloud amount is measured visually by estimating the fraction (in eighths or oktas) of the dome of the sky covered by clouds. A completely clear sky is recorded as zero okta, while a totally overcast sky is recorded as 8 oktas. The presence of any trace of cloud in an otherwise blue sky is recorded as 1 okta, and similarly any trace of blue in an otherwise cloudy sky is recorded as 7 oktas.
