Averaging by its very nature smooths: removing peaks and troughs. Temperature data tends to be cyclical, whether on a one-minute, or thousand-year scale. The Australian Bureau of Meteorology has made a habit of smoothing when it is convenient and using extreme values otherwise. Take their one-minute temperature data from Canberra Airport: super-sensitive electronic equipment now records the highest, lowest, and last second of each minute and reports the highest second as the daily maximum temperature. Back in 2019 I purchased some of this data to test the Bureau\u2019s claim that averaging the data would make no difference. I found that averaging the last one-second of each minute always gave me a lower maximum temperature. This is because the difference between the the highest and the last second could typically be 0.7 degrees Celsius as shown in Figure 17 \u2013 that is from a comprehensive report I co-authored in 2020. I have so far been unable to get this report published in a suitable peer-reviewed journal perhaps because it contradicts the Bureau\u2019s much lauded Ayers and Warne (2020) analysis that comes to the opposite conclusion.<\/p>\n
