Data Suppliers

SILO constructs products using data provided by the Australian Bureau of Meteorology (BoM) and various other suppliers. For most products users can choose between versions which have been constructed using:

  • only official data provided by the BoM
  • all available data, which may include data from private landholders, natural resource management groups, commercial organisations and Government agencies, as well as the official data from the BoM.

SILO uses data from these additional sources to improve the quality of our products. While the BoM maintains a nation-wide network of recording stations, the number of stations (or more precisely, the spatial density of the station network) is insufficient to construct gridded rasters which are reliable. In some areas, typically in regions of uniform topography and relatively close to urban centres, the station network is sufficiently dense to construct reliable rasters for some variables. However in most agricultural regions the station network is relatively sparse. In such areas it is not possible to reliably interpolate… the observed data, especially for variables such as rainfall, with can vary significantly over very short distances.

The table below lists the organisations which have provided, or in some cases continuously provide, data which are used in SILO products.



Bureau of Meteorology

Queensland Government

Partners in the Queensland Government’s DCAP program
(provide a link to the new LP page for displaying the data coming from Dave’s new rain gauges)

Condamine Alliance

Private landholders


SILO welcomes contributions of data, such as rain gauge records. If you have reliable records that you would like to contribute, please contact us.

…Interpolation is a technique SILO uses to estimate the value of a climate variable at a location where an observed value is not available. Interpolation is used to construct our gridded rasters, and to “patch” missing values in our time-series datasets at station locations.
