Users should be aware that SILO data are constantly evolving:
Recent datasets grow rapidly as new observational data are added (while some stations report in real-time, it may be several months until data are received from all stations);
Older datasets may grow slowly as hand written (paper-based) records are digitised; and
All datasets may undergo minor changes as a result of error detection programs undertaken by SILO and the Bureau of Meteorology.
Clients requiring a static dataset for analysis should download and archive their own copy of the data.
Significant updates to SILO are listed below:
25 September 2019
Interpolated rainfall datasets for the period 1 January 2017 to 24 September 2019 were replaced with new datasets. The original datasets were inaccurate due to an error in the software which generates SILO’s interpolated rainfall datasets.
Parameters used for normalising monthly rainfall prior to interpolation were recomputed. For further information about the normalisation procedure, please refer to the SILO reference paper.
Modifications to the observed data, station coordinates or algorithms affecting derived data are listed below:
None to date.
