In February I wrote about persistent errors in BoM min temperature anomaly maps over a station in the south west of the Northern Territory – errors I first noticed in 2011.
“Australian Bureau of Meteorology still have persistent errors in their temperature anomaly maps”
The errors are still there for the entire 72 months 2002-2007 – see my new animation.
How long will it take the BoM to recognize the reality that their AWAP data has these huge NNTHS errors?
My animation is pointing to other persistent errors in the NT and Qld data – but let’s concentrate on getting the BoM to eradicate the NNTHS first.

How long does it take the Australian BoM to fix a simple 10°C error in their AWAP temperature anomaly maps?
On the 5th I posted – Southwest Queensland heat wave 2 July 2014 – pointing out the 10 degree error for the Bedourie max on 2 July.
After a couple more days the 30 was fixed to a 20 here.
But I see this morning 14th July after another week passes – that the 10 degree error is still in the AWAP maps.
How can the BoM which has been in existence for over a century – not have routine operating procedures in place to ensure that these tiny tasks are promptly done?
Would a 10 degree cold error have been repaired quicker?
The original error was only spotted because it was a huge standout anomaly.
What about errors that are more subtle and harder to spot?
What confidence can we have in the routine BoM AWAP temperature anomaly maps?
Global warming strikes Queensland – Brisbane has coldest morning in 103 years

Southwest Queensland heat wave 2nd July 2014
I noticed this aberration in BoM max anomaly maps –
on checking I see that Bedourie on 2 July recorded 19° at 3pm. Yet they have 30° recorded here.
So we are expected to believe that the temperature rocketed 11 degrees quicktime
It just amazes me that such an obvious outlier can get through BoM processes.
And I like the way the contouring maths generates the next layer up red anomaly all on its own.
There are not that many Qld stations reporting on this page – that given BoM computing power and the presumed importance of filtering out errors – a staffer could easily tick through the Qld list in 5 or 10 minutes each day eyeballing for obvious errors.
Great to see Andrew Bolt exposing that more and more researchers are speaking out how temperature data is being altered to cool the past

Australian Bureau of Meteorology (BoM) has a long history of ignoring faults in HadCRU global temperature series – temperature data that birthed “global warming”
In 1986 the Jones et al team published papers for both hemispheres compiling temperature data from weather stations into long term trends.
Northern Hemisphere Surface Air Temperature Variations: 1851-1984
P.D. Jones, S.C.B. Raper, P.M. Kelly, and T.M.L. Wigley, R.S. Bradley and H.F. Diaz; Journal of Applied Meteorology: Vol. 25, No. 2, pp. 161-179.
and
Southern Hemisphere Surface Air Temperature Variations: 1851-1984
P.D. Jones, S.C.B. Raper, and T.M.L. Wigley;
Journal of Applied Meteorology: Vol. 25, No. 9, pp. 1213-1230.
The journal papers are about what Jones et al want readers to see. The Northern Hemisphere TR022 and Southern Hemisphere TR027 books published by the US Dept of Energy (long term funders of Professor Jones) tell you more about what was done.

The BoM did not comment to the journal despite Jones et al use of all Australian urban heat island affected State Capitals. In fact there were no comments on either journal paper published in the Journal of Applied Meteorology – an amazing fact considering this huge research project touched on all the worlds met services. Maybe comments were sent in to the editor but never made it to print – somebody might know.
Then in 1988 a critique of the papers by Dr Fred B Wood appeared in an Elsevier journal. Wood, F.B. 1988, “Comment: On the need for Validation of the Jones et al. Temperature Trends with respect to Urban Warming”, Climatic Change 12, 297-312.
There was a reply. Wigley, T.M.L. and Jones, P.D. 1988; “Do large-area-average temperature series have an urban warming bias ?”, Climatic Change 12, 314-318.
Dr Fred B Wood was from the Office of Technology Assessment, United States Congress and no previous publication of his was referenced in his Comment – although he did gratefully acknowledge “…useful suggestions and/or critiques of earlier drafts…” from 16 named people and several anonymous reviewers. So it makes for a fascinating story that nobody with a meteorology or climate background commented on the Jones et al papers which touched on data from every “weather service” on planet earth and nobody stood up as a co-author with Dr Fred Wood.
In 1990 the BoM produced a draft paper which was circulated to the IPCC – M.J. Coughlan, R. Tapp and W.R. Kininmonth; 1990, “Trends in Australian Temperature Records” (scroll down). Coughlan, et al 1990 studied urban/rural pairs at Capital cities and concluded re urbanization affected temperature trends – “These estimates are greater than those of the trends this century, reported by Jones et al. (1989), in annual mean Southern Hemisphere air temperature…”
I assume the BoM draft sunk without trace at the IPCC.
In 1991 I examined the Australian segment of the Jones et al compilation resulting in a draft paper – The Australian Record on “Global Warming” (TARGW) – Tasman Institute 1991 review of the Australian component of temperature records used in the 1986 Jones et al Southern Hemisphere paper, Executive Summary online scroll down page.
TARGW was circulated to the BoM who were generally critical but agreed –
[1] that capital cities data should be viewed “with suspicion” – and
[2] also that “long term stations (were) overlooked in the global dataset”.
More of TARGW is also online in a 2009 blog post – Jones et al 1986 methodical insertion of warming bias.
As an example of BoM criticism that I find inconsistent they said “Cunnamulla should not be considered a neighbouring station of Charleville”. OK I can see they are 180km apart but over flat terrain – it is the network we have, there is no other, the smaller centre shows less warming and of course Cunnamulla was rejected by Jones et al and Charleville trucated at 1951.
Where the BoM is inconsistent is I have never seen that they have criticised Jones et al who often compare Australian stations in excess of 1000km apart – see examples in table.
Remembering the Jones et al 1986 temperature station comparisons were often over huge distances – ridiculous distances sometimes over 1,000km
I have just been pulled up by George Bailley for comparing Ceduna temperatures to Fowlers Bay (western South Australia) which he said were 118km apart.
This comment from GB was at my earlier post – The BoM ACORN SAT dataset disaster rolls on – fatal minimum>maximum errors can not be repaired until “second half of 2014” –
Yet when Professor PD Jones and his team birthed “global warming” with their two hemispheric papers in 1986 they often compared stations over 1000km apart – see table below with Australian examples. The Australian Bureau of Meteorology made no comment about the Jones et al 1986 paper quoting these ridiculous station comparisons.
Data in the table above is from this book – html version – Jones PD , Raper SCB, Cherry BSG, Goodess CM, Wigley TML, (1986c) TR027 A Grid Point Surface Air Temperature Data Set for the Southern Hemisphere. Office of Energy Research , Carbon Dioxide Research Division, US Department of Energy. Under Contract No. DE-ACO2-79EV10098 –
When GB has written to Professor Jones pointing out the huge distances between his station comparisons – and tried to convince Professor Jones that his comparisons should not exceed 100km – then I might take more note of comments by GB.
In 1988 Dr Fred B Wood published a useful critique of Jones et al 1986 and he addressed this distance issue – which Wigley & Jones termed a “red herring”.
Climate Council (Australia) says Autumn 2014 is abnormal
Remember the Climate Council was birthed by ex staffers from the Climate Commission which was disbanded by the Australian LNP Government elected Sept 2013. Climate Council Seasonal Update: Abnormal Autumn – Looks to me as if their cherry picked warm period 8 to 26 May is borrowed from the BoM – Special Climate Statement 49 – an exceptionally prolonged autumn warm spell over much of Australia
Here is a time series chart of Australian Autumn mean temperature anomalies. Not sure what is abnormal. Remember these time series charts are built from ACORN SAT data.

Sydney is the only prominent site I can see that had an all time record warm Autumn. Birdsville qualifies too. Any other candidates?
A fail for Australian Bureau of Meteorology temperature Outlooks for Autumn 2014
Interesting with all the BoM publicity about Autumn and May breaking warm records – the BoM Outlooks for Autumn turned out so dud.
Trying out animations – first maxtemp Outlook plus resulting real world anomaly.

Example of Australian Bureau of Meteorology trumpeting cherry picked temperature records when monthly data shows no records
We have all heard media blah about the warm May in Sydney such as this today in the SMH – Sydney’s balmy autumn breaks temperature records –
The Bureau of Meteorology (BoM) has just issued – Special Climate Statement 49 – an exceptionally prolonged autumn warm spell over much of Australia –
On page 5 of SCS 49 the BoM make an explicit connection between Australian warming and “…warming….for the globe…”.
Now I have not got a fraction of the computing power or resources, time etc that the BoM has – so I just want to illustrate my point by reference to the records quoted for Giles station 13017 in the BoM Table 2 – Records set at ACORN-SAT locations for the greatest number of consecutive days with minimum temperatures at or above the listed threshold in the period 1 May to 30 June.
Here is the BoM claim for Giles –
But to put May minimum temperatures at Giles in better perspective – here is my table showing Giles May minimums have been warmer several times in the recent past.
So the BoM claims for Giles in their Table 2 do not amount to a cupful of warm spit in terms of global warming – or Australian warming for that matter.
Hoping readers can checkout other examples.
I wonder what this BoM Special Climate Statement 49 cost – what staff hours went into it?
