Gridded Köppen classification metadata


Title Köppen climate classification (base climate related classification datasets)


Custodian Bureau of Meteorology
Jurisdiction Australia


Abstract The grids shows the Köppen classification indicies across Australia in the form of two-dimensional array data. 
The classification is based on the standard 30-year period 1961-1990.

Data Quality

Lineage The classification was based on mean monthly and annual rainfall, maximum temperature and minimum temperature grids. 
For more information see : Stern, H., de Hoedt, G. and Ernst, J. 1999. Objective classification of Australian climates. Aust. Met. Mag. 49 (2000) 87-96. 
The base grids were generated using the ANU (Australian National University) 3-D Spline (surface fitting algorithm). 
The resolution of the data is 0.025 degrees ( approximately 2.5km) - as part of the 3-D analysis process a 0.025 degree resolution digital elevation model (DEM) was used. 
All input station data underwent a high degree of quality control before analysis, and conform to WMO (World Meteorological Organisation) standards for data quality. 

Grid-point indices on the classification grid are as follows: 
42 rainforest (monsoonal) 
41 savanna 
37 rainforest (persistently wet) 
36 rainforest (monsoonal) 
35 savanna 
34 no dry season 
33 distinctly dry summer 
32 distinctly dry winter 
31 moderately dry winter 
24 hot (persistently dry) 
23 hot (summer drought) 
22 hot (winter drought) 
21 warm (persistently dry) 
15 hot (persistently dry) 
14 hot (summer drought) 
13 hot (winter drought) 
12 warm (persistently dry) 
11 warm (summer drought) 
9 no dry season (hot summer) 
8 moderately dry winter (hot summer) 
7 distinctly dry (and hot) summer 
6 no dry season (warm summer) 
5 moderately dry winter (warm summer) 
4 distinctly dry (and warm) summer 
3 no dry season (mild summer) 
2 distinctly dry (and mild) summer 
1 no dry season (cool summer) 
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.
