| The Bureau of Meteorology can provide you with monthly and annual average or actual gridded datasets for Australia. These datasets can be ported into
a GIS or similar visualization system, and can be used to investigate the data or generate maps. A list of these gridded datasets is shown below.
|
| |
| If you wish to obtain the gridded datasets, we will need to know:
|
- The type of grid (meteorological element) you require - see table below.
- The period - month or months and/or annual (* annual only).
- The area you need - all Australia, a particular State/s or define a decimal degrees latitude/longitude boundary box.
- The output format or formats you require - see table below.
|
| Note: Prior to requesting spatial data, please ensure that the available file formats are compatible with your GIS software.
The Bureau does not provide advice on the use of proprietary software packages. |
