Climatic Atlas of Australia - Rainfall CD ROM
|
|
Mean monthly and mean annual rainfall maps.
The maps show mean rainfall values across Australia. The mean data
are based on the standard 30-year period 1961-1990. See LINEAGE below
for more information.
|
The Rainfall CD contains a range of infomation
including:
- high resolution mean monthly and mean annual rainfal maps;
- mean monthly and mean annual gridded rainfall data;
- a map viewer and data extraction tool.
The map viewer interface provided with the CD allows you to determine
the rainfall values at any location across Australia. The CD also
includes explanatory text describing the data. |

Gridded data were generated using the ANU (Australian National University)
3-D Spline (surface fitting algorithm). As part of the 3-D analysis process
a 0.025 degree resolution digital elevation model (DEM) was used. Approximately
6000 rainfall stations were used in the rainfall analyses. All input station
data underwent a high degree of quality control before analysis, and conform
to WMO (World Meteorological Organisation) standards for data quality.
