The mean value, also known as the average, is one of the most common statistics used to provide an estimate of what is most likely to happen. It is not necessarily equal to the most commonly occurring value, which is known as the mode, but for most elements it will be close. You can learn more about how we calculate statistics.
An objective analysis technique is applied to the station-based data to produce regular gridded datasets covering Australia. Satellite data and model output are already in the form of regular gridded datasets, so no further analysis is required. The colour maps are produced from these gridded datasets.
You can find out more about the format of the gridded datasets and the analysis technique is described in the metadata provided for each map series.
