|Title||Seasonal rainfall classification (base climate related classification datasets)|
|Custodian||Bureau of Meteorology|
|Abstract||The grids shows the seasonal rainfall classification indicies
across Australia in the form of two-dimensional array
The classification is based on 100 year period (1900-1999).

|Lineage||The classification was based on median annual rainfall (November to April, May to October and seasonal incidence).
The seasonal incidence is determined from the ratio of median rainfall for periods, November to April / May to October and May to October / November to April.
For more information see: Gaffney.D.O. 1971, Seasonal rainfall Zones in Australia, Bureau of Meteorology, Working paper No 141.
The base median rainfall gridded data were generated using the Barnes two-dimensional analysis. The grid resolution of the data is 0.25 degrees (approximately 25km).
Grid-point indices on the classification grid are as follows:
1 summer dominant (more than 1200)
2 summer dominant (650 - 1200)
3 summer dominant (350 - 650)
4 arid (less than 350)
5 summer (more than 1200)
6 summer (650 - 1200)
7 summer (350 - 650)
8 uniform (more than 800)
9 uniform (500 -800)
10 uniform (250 500)
11 winter dominant (more than 800)
12 winter dominant (500 800)
13 winter dominant (250 500)
14 winter (more than 800)
15 winter (500 800)
16 winter (250 500)
|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||Grid point data are post processed.
