Gridded temperature/humidity metadata


Title Thermal Climate Zone Classification (base climate related classification datasets)


Custodian Bureau of Meteorology
Jurisdiction Australia


Abstract The grids shows the temperature/humidity classification indicies across Australia in the form of two-dimensional array data. 
The classification is based on the standard 30-year period 1961-1990 rainfall and temperature grids. 
See LINEAGE below for more information.

Data Quality

Lineage The classification was based on average January maximum temperature, average 3 pm January water vapour pressure, 
average July mean temperature and annual heating degree days grids. 

For more information click on the following site: 

These 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: 
1 hot humid summer 
2 warm humid summer 
3 hot dry summer, mild winter 
4 hot dry summer, cold winter 
5 warm summer, cool winter 
6 mild warm summer, cold winter 
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.
