The Australian Broadcasting Corporation (ABC) uses data supplied by leading scientific bodies including the Bureau of Meteorology, National Oceanic and Atmospheric Administration and National Aeronautics and Space Administration (NASA).
For daily data, such as the temperatures used in weather reports, raw data is used.
Homogenised data is always used when it is published by the Bureau of Meteorology for climate related stories as there is no alternative dataset. For example, when talking about climate trends over large areas like the Australian land mass, the ABC typically uses homogenised data, as there is no meaningful alternative. The ABC understands this is the standard approach taken by credible scientific bodies.
For general news reporting, the ABC looks to the position taken by leading scientific agencies on whether to use raw or homogenised data.
The methods used by the Bureau of Meteorology to homogenise data have been peer-reviewed, and have been subject to additional independent reviews which have confirmed they are world-leading.
When newsworthy, the difference between homogenised and raw data is discussed, as it was in the following stories:
