Description |
|
| Abstract | Three-monthly and annual rainfall variability grids. The grids show rainfall variability indices across Australia in the form of two-dimensional array data. The indices are based on the period 1900 to 2003. See LINEAGE below for more information. |

Data Quality |
|
| Lineage | Rainfall variability was based on 104 years of monthly and annual gridded data. These gridded datasets were generated using the Barnes two-dimensional analysis. The grid point resolution of the data is 0.25 degrees (approx 25km).All available rainfall stations were used in the analyses, and the input station data underwent standard quality control. Rainfall variability was calculated using the following formula: Rainfall variability = (90th percentile - 10th percentile) / 50th percentile. |
| Positional Accuracy | The observational (station) data on which the analyses were based have an associated accuracy of the order of 0.01 degrees (approximately 1km) or better. |
| Attribute Accuracy | Not applicable |
| Logical Consistency | Not applicable |
| Completeness | No missing data |
