The ACORN - SAT dataset is an analysis of
Australian temperature observations since 1910 that provides a record of temperatures that can be compared through time.
This test found that the «no - Australia» southern hemisphere temperature was typically 0.10 — 0.15 °C cooler than the full southern hemisphere dataset between about 1878 and 1893, suggesting that
Australian temperature observations incorporated into the HadCRUT4 dataset were likely to be unrealistically warm during this period.
