Particularly since there are no cooling anomalies over this time.
The extent to which correction goes one way is exaggerated; people here like to focus on individual cases of that kind. [Here millions of numbers are downloaded if available] A large proportion falls in the months December through to March with the driest months being August/September. Here is his summary of the changes made as a result of the release of ACORN-SAT in 2012: This leaves open that both could be wrong. The following figure, for the Mackay minimum temperature (Tmin) data, shows an example where there is a failure to make a necessary adjustment: In the figure above it can be seen that the accumulated error of around 0.5C in 1910 arises from a failure to detect/correct the onset of a transient non-climatic warming in 1990. I am working to produce a compilation of all the worst case errors, all of which (so far) involve excessive cooling of early data.

For example, two neighboring regions with the same shade of color may actually have different absolute mean temperatures. See average monthly temperatures below. Each day. It will be at https://kenskingdom.wordpress.com/, The ACORN station catalogue says: (my bold). Also, the trick of commencing the series in 1910 neatly avoids the very high temperatures of the Federation Drought of 1896-1903, where measured temperatures were higher than today, and there was a significant human death toll in the remote country regions. Chase says he sees “cool” spots. [was it burned?] You need to look at the absolute temperatures. The idea that a small area can warm more than the vast areas surrounding it, including areas with very similar features, over a long period, is extremely unlikely. Find the most current and reliable 14 day weather forecasts, storm alerts, reports and information for Mackay, ID, US with The Weather Network. Nor does the “trend consistency of the other datasets, including BEST (Cairns), and the small size of residual fluctuations in the difference plots, provides strong evidence of their mutual validation.” Long-term trends are strongly influenced by local UHI and difference plots provide nothing more than point comparisons–not any serious validation. I asked the online Wolfram-Alpha Guru this question: “What is average temperature in Australia over last 100 years?” Data from the Te Kowai Experimental Station (33047) located 5 km west of the town were used between 1947 and 1959, with data from 1959 to 1965 used to merge the record with that at the Meteorological Office. The article doesn’t plot the ACORN trend relative to its neighbors. There are other oddities in BoM temperature anomaly maps. Weather stations report no annual snow. The Mackay Post Office data is “http://www.bom.gov.au/jsp/ncc/cdio/weatherData/av?p_nccObsCode=122&p_display_type=dailyDataFile&p_startYear=1949&p_c=-218610327&p_stn_num=033046”. Such a Commission would ask hard questions about the BOM data breaches,

“So lets start asking the usual hard questions.”

Which would not be nearly so “scary” as shades of red. The warmest time of year is generally early to mid January where highs are regularly around 88.3°F (31.3°C) with temperatures rarely dropping below 73.3°F (22.9°C) at night. – Yet amazingly the vast majority of homogenisation cools the past and warms the present. Cool spots? It’s right by the coast…maybe they’ve found some of Trenberth’s missing heat? Sounds like the Met Office uses the racetrack temperatures as it has no temp recording facilities and is lower than the airport? I wondered if the different topography at Mackay , compared to the rest of the East Coast, might have exacerbated that rise. I quoted their statement here. All I am after is your protocol or method of validation. (click on “sources” to see the entire list), Try it yourself! ‘The Meteorological Office site (33119) commenced observations in 1959, and no known site moves have taken place. The only thing I’m interested is whether it’s said “Mac-Kay” or “Mac-Aye.”.
They were small crayfishing towns until the 1980’s when they became popular summer holiday home area for people from Perth. Ideally a reference series must have no more than “small” inhomogeneities. The graph below shows the average snow on the ground in Mackay (in). Anomaly changes should be lower for coastal regions due to ocean buffering. temp. Units, as clearly stated, are °C/decade.

Read below for more weather and travel details. Nick, ““warmed relative to other towns nearby” The graph below shows the % chance of rainy and snowy days in Mackay. The figures given represent multiple adjustments of previous data.

Then MacKay would be rendered as “hotter” on these kinds of charts. An error free map would be pretty uniformly pink, at about 0.15C/decade. Divided into 99 districts. lowering for the 2012 starting Acorn data set. The area is somewhat temperate — in the 48th percentile for pleasant weather — compared to tourist destinations worldwide. The BOM must have such a reference.
