The Bureau’s climate data experts have carefully analysed the digitised data to create a consistent—or homogeneous—record of daily temperatures over the last 100 years.The ACORN-SAT homogenised temperature database comprises 112 carefully chosen locations that maximise both length of record and network coverage across the continent Additionally, the Bureau maintains multiple temperature datasets—analysed in different ways—to provide a consistency check on the accuracy of temperature observations.The Australian Climate Observations Reference Network – Surface Air Temperature (ACORN-SAT) dataset has been developed to monitor climate variability and change in Australia.The dataset employs the latest analysis techniques and takes advantage of digitised observational data to provide a daily record of Australian temperatures over the last 100 years.The Bureau maintains a layered approach to correcting data errors.Each day, automated and semi-automated quality control systems identify observational errors using methods such as comparison with data from nearby sites.
A number of major events occurred during the time of Korra's Team Avatar, including the Anti-bending Revolution, the events surrounding Harmonic Convergence, the insurrection of the Red Lotus, and the formation of the Earth Empire.
The data is robust and comparable through time, which will enable climate researchers to better understand long-term changes in monthly and seasonal climate, as well as changes in day-to-day weather, such as the frequency of heat and cold extremes.
The history of instrumental weather observations in Australia stretches back to European settlement.
The history of this world can be roughly divided into two parts, the time before the Avatar and the time of the Avatar.
Prior to the Avatar's creation, lion turtles served as the protectors of mankind, allowing the humans to erect cities atop their shells. Whenever the inhabitants of their cities would venture into the Spirit Wilds, the creatures would bestow the people with the ability to bend the element the turtle was affiliated with; the power was to be returned upon their reentry to the city.
