Sydney temperature history – BoM raw data compared to ACORN adjusted data

Here is Sydney raw max & min annual temperature history –

This shows raw compared to ACORN also annual – you easily see where the effective adjustments are concentrated.

From 1 Jan 1983 on to present day there are no adjustments made to the daily max data. There are however some days when the raw reading is discarded to leave a data gap in ACORN. In the case of minimums (nightime) the data has no ACORN adjustments from 1 Jan 1964 to present day. But like the max – ACORN finds quite a few minimums not fit for ACORN.

To me it looks like machine driven stroking & tweaking.

RSS satellites find Australian lower troposphere anomalously cool during March 2014 – BoM surface data finds a warm anomaly

RSS finds the same general shape as the BoM mean anomaly – when you make a mean anomaly map for March at the BoM you see Perth and Hobart were warmest.

The Time Series chart shows the BoM anomaly was about +0.75 degrees. Fascinating that there should be such a difference with RSS – considering the lower troposphere is such a gossamer thin skin when considered on the scale of our wide brown land.
Interesting too that RSS found all three southern hemisphere land masses were cool in March. I bet the big surface datasets will not agree.

BoM says re Hobart on 1st April 2014, “..31 degrees Celsius was the hottest April day since records started in 1881.”, but history shows sites nearby experienced several relatively hotter events

The ABC reports – Records melt as Hobart swelters through hottest April day in 132 years
Checking hottest April day statistics at this BoM page – just amend the station number in the URL.
Checking daily data a month at a time in District 94 on Australian Weather News AWN – April 2005 at AWN shows the two hot days on 1st & 2nd.

The article could have been more balanced by pointing out other hotter events in the very small and variable District 94. IMHO Tuesday was just another early April hot day where the peak max happened to fall at central Hobart. I wonder if we should expect more balance from our scientists at the Bureau of Meteorology.

The Australia Bureau of Meteorology says Perth’s record-smashing summer was “madness” – how about summer where you were?

Here is a map of the maximum temperature anomalies for summer.

WA’s ‘mad’ summer is proof of climate change: BoM expert – PerthNow
The national average was under +0.5°C. I think the Perth BoM needs a Bex a cuppa tea and a good lie down.
below you can see each day of the Perth summer set out in the 3 months from Australian Weather News.Pale Blue is the background colour for minimums which presumably signifies a range around average with Yellow highlighting warm nights and a brighter Turquoise for cooler nights. Pale Pink is background for max which also seems to signify a range either side of average – Turquoise is cool, Yellow is warm – Buff is hotter. The top row is minimum or night temperature – second line is day or maximum. So just running your eye along you get the impression of the extent of cool spells, warm spells and periods near average.

Cool end to summer puts kybosh on warmists hopes for “hottest summer whatever” media headlines

Earlier in February media weather reports were carrying hints and winks that Canberra was “on track” for the “hottest summer evah”. Sadly for the warmists the Australia wide cooling towards the end of summer will have had the usual suspects combing through data assiduously searching for a record anything to trumpet from somewhere.

We will see.

Launceston temperature history illustrates how BoM inserts a large warming trend where raw data shows little change over 100 years

In 2012 the Australian Bureau of Meteorology brought out their ACORN SAT highly adjusted and warmed temperature data for just over 100 stations with all data commencing in 1910. Launceston starts in 1885 but the early data has gaps so we start at 1910 comparing raw data trends with warming trends from the BoM highly adjusted ACORN SAT.

It looks clear that the data as collected over more than 100 years shows no significant warming.
Over twenty years ago I built the two Australian long term series
Average of 25 Regional and Remote Stations –
Average Temperature for the 6 Capital Cities
It looks as though I had not found the Launceston data at the time the above was contructed in 1991.
The aim is to update more long term stations data as collected and contrast with ACORN SAT.

Australian Bureau of Meteorology still have persistent errors in their temperature anomaly maps

In June 2011 I began drawing attention to what I termed the “National Night-time Hotspot” (NNTHS) – I told the BoM about this and I thought I noticed an improvement in their maps. However I have noticed the NNTHS is still writ large in BoM minimum temperature anomaly maps for all the years 2002-2007 see my animation – NNTHS makes a cameo appearance again in 2011.

Am I seeing a “son of NNTHS” in the Jervois district south east Northern Territory in the years 2008, 2009, 2010, 2012, 2013 ?

These examples are just the standout most obvious outlier errors.

Australian Bureau of Meteorology takes urban heat island (UHI) into account when announcing heat records

I have just been told by the Parliamentary Secretary to the Minister for the Environment – Senator the Hon Simon Birmingham – that when _ “…the Bureau publishes relevant records of weather and climate occurrences and extremes based on observations from sites around the country.”
The BoM is “…taking into account any urban heat island effects in towns and cities.”
Can anybody find me an example of this? Click to read my 12 Nov 2013 email to Minister Hunt and their reply
