Dial M for mangled Wikipedia and Environment Canada caught with temperature data errors.
Watts Up With That? ^ | April 22 , 2010 | Anthony Watts

Posted on 04/25/2010 12:09:21 PM PDT by Ernest_at_the_Beach

UPDATE 4/23 4PM: I’ve been in contact with the Eureka Weather Station manager, and despite the incredible nature of the temperature jumps that are outside of normal experiences, such as July 14 2009,  they do appear to be real. The METAR coding errors are another issue. I have many pictures now, plus a plan map, and a better meteorological insight than what can be gained from the meager online metadata. I’ll have an updated post later tonight or tomorrow – Anthony

Ecotretas find more cases of missing “M”s and mangled data in METAR reports making it into climatic temperature data.  I’ve reposted his findings below and added some of my own notes [in brackets] to strengthen his findings. This time it’s Eureka, Nunavut, Canada. From “Up Here” magazine:

The first High Arctic Weather Station in history, Eureka was established in April 1947 at 80-degrees north latitude in the vicinity of two rivers, which provided fresh water to the six-man United States Army Air Force team that parachuted in. They erected Jamesway huts to shelter themselves and their equipment until August, when an icebreaker reached Eureka – as it has every year since – and brought permanent buildings and supplies. For decades after that, small, all-male crews would hunker down for entire winters, going a little stir-crazy from the isolation.

As I pointed out last Saturday there’s a common reporting flaw in world meteorological stations that use the METAR weather data format to report their hourly temperatures. Just one bad report in a cold location in the Arctic or Antarctic is enough to throw off the whole month’s worth of data when averaged. And it is monthly data that is used for climate. The all time high temperature error identified below has found it’s way into Wikipedia as “factual” when it is clearly wrong.

Some METAR and other kinds of unidentified errors also seem to be finding their way into official Environment Canada data. I’ve made screencaps. Given the importance of this weather station as the last surviving  GHCN station that far north, also used in GISS, you’d think better quality control would be done, particularly when EC has a statement about data quality on each data page. What has been found seems to point to a corrupted dataset there.

As Anthony Watts pointed out at Watts Up With That, the Eureka station registered the biggest rise in temperature probably seen on the Earth’s surface: 86ºC in one hour, on March 3, 2007!

Now this data is available on Weather Underground, but seems not to exist in Environment Canada. The graph differences are clear below:

But that seems not to be the case in other examples. Take January 1st, 2007, for instance. Both Weather Underground and Environment Canada agree: there was a mighty spike at noon. Seems like the “M” problem affects both:

[Here's the METAR data with the missing "M", note at  11AM the M reappears]

There are times where differences are not so big, but the “M” problem is still there. Check the images from Weather Underground and Environment Canada for September 26, 2006:

Other times, changes are so significant, that something must be wrong. Check out the temperature rise on June 20, 2005. On the left, the weekly graph from Weather Underground shows a great surge in temperatures, confirmed by the Environment Canada graph for the day.

=====================================

Thanks to Ecotretas for his sleuthing, I’m sure there are many more like this yet to be discovered. It seems with Eureka, more is going on than METAR errors. The temperature rises reported seem impossible given the meteorological conditions, and because they seem to be automated, suggest sensor error or perhaps sensor environment contamination (like a vehicle or other heat source). If you look at this 1997 image from Wikipedia (and click it to get the super hi-res version and pan around) you’ll see a number of vehicles near buildings. Where is the temperature sensor? – I don’t know, but if someone can find out it might shed some light on this mystery.

Yesterday from WattsUpWithThat?:

Inside The Eureka Weather Station

**********************************EXCERPTS**********************************

24 04 2010

In my previous post Dial “M” for mangled – Wikipedia and Environment Canada caught with temperature data errors. we identified some problems with temperature data from the Eureka Weather Station.

Today I’m starting what may be a two or three part series having a detailed look inside the Eureka Weather Station and the data it produces. Thanks to the manager of the station Rai LeCotey, we have a lot of new information that had not previously been available on the web. Mr. LeCotey has been most gracious and forthcoming and I commend his openness, which as we have seen in Climate Science, is a rare quality. Here’s an aerial view of the station.

click for a larger image

Ecotretas and I looked at  a number of what we identified as errors in data from Eureka, Nunavut, Canada weather station. Some errors are real, such as the January 1st 2007 METAR error (caused by transcription error).

We identified what we thought were errors on July 13th and 14th. The Station Manager Mr. LeCotey says that the July 14th new record high temperature “error” was real (meaning meteorological data, not a transcription error), and a function of wind direction bringing air from the North that has been warmed by terrain.  He also says he’s working to get the error on Jan 1 2007 corrected in the record. He’s sent along some photo documentation of the July 14th 2009, event. We’ll get to that in a subsequent post, but first some background on the station itself.

Here’s what the Meteorological Instrument Complex looks like:

It’s important to clean up what’s going on in the Arctic.
Holdren’s keynote shows a Hansen et al. globe from 2006, with the big deep-red Arctic, suggests a disruptive(!) climate change now.
Strong words. Weak facts.

Very impressive, well, sort of … if you are not a WUWT reader.
Haven’t we seen some graphs lately, showing temperatures, ice cover, sea level over time with not a bit of disruption anywhere?

Funny thing — ash will be coating the Arctic, but ash will also be blocking sunlight [from Iceland]. Pole flipping theory to resurface you think? Ice melting in the north [dark ash absorbing sunlight] and thickening in the south.

Anthony, Just in from Mark E. Gillar and his radio program.

Chris Horner Drops Bomb: Predicts first major ethics scandal of
the Obama Administration to be revealed on Monday.

April 24, 2010

This morning on Global Cooling Radio, Chris Horner, author of the recently released book, Power Grab: How
Obama’s Green Policies Will Steal Your Freedom And Bankrupt America, revealed that a major ethics scandal
involving someone in the Obama administration will be unveiled on Monday. Here is the complete quote that
comes at the 29:01 mark of the interview:

“You’re going to see the first ethics scandal in the Obama administration. We’ve got our hands on some internal
documents revealing a serious conflict of interest at a very high level on these green jobs and stimulus and the
policies that Carol Browner was talking about. It isn’t Ms. Browner, but it is someone tied to Al Gore.”

- Chris Horner

Note: The statement comes at the 29:11 mark in the interview.

It’s refreshing to see the Eureka staff are highly professional — not surprising though, given what they volunteered for.

The explanation for the brief, but legitimate warm spell argues against using just the low and high for the day to compute the average. Might this explain some of the difference between the surface data and the satellite data (amongst all the other explanations)?

jason (05:26:33) :

“Also are we saying that climatologists are not aware of the quirks of Eureka and are not adjusting the data. ”

I have also worked extensively in the research area of meteorology. As such, I have had dealings with some climate scientists. My impression is that many had little knowledge as to how weather data is actually collected and what the potential errors may be. I believe they assume that local effects are just averaged away on the longer term. It is one of the reasons that many operational meteorologists are very skeptical of the whole climate science area.

Now looking at comments to the article posted to start this thread......:

********************************EXCERPTS*****************************

And regarding Browner of the EPA:

*************************************

Henry chance

Just for the record.

Carol Browner, former Clinton administration EPA head and current “Obama White House climate czar, instructed auto industry execs “to put nothing in writing, ever” regarding secret negotiations she orchestrated regarding a deal to increase federal Corporate Average Fuel Economy (CAFE) standards. Rep. James Sensenbrenner, R-WI, is demanding a congressional investigation of Browner’s conduct in the CAFE talks, saying in a letter to Rep. Henry Waxman, D-CA, that Browner “intended to leave little or no documentation of the deliberations that lead to stringent new CAFE standards.”

..So why do we keep complete and accurate records?

I like this summary:

*******************************EXCERPT***********************************

IAmDigitap

Every one of them [ the general pool of media the government criminal ring to terrorize people with the end of the world got it's hands around: wikipedia, government reporting, government (university) review of scientific literature ]

Every one of them is being revealed to be fake , one,

by one.

Al Gore the guy who ”had a great idea of how to transform the economy he wanted to show the people… SMART, SMART MEN, He KNEW, had APPROVED it” -
carbon credits opened at $22 per ton. . . opening at Z.E.R.O. after
dozens of arrests all over Europe where he worked with Germans and others

Hansen with his legendary record of false predictions that , for some years, was literally a CAT CALL to shut a bunch of globel warming HICKS up.

Mann with his “school of statistics for climatography-ism-istic studies in the magic-sphere”

The entire system recently adjudicated as “not mathematics we endorse as being actual statistics” by the Royal Statistical Society…

If their statistics aren’t even endorsed by the people that teach statistical modeling

they aren’t qualified to make climate models and submit them at ALL.

‘WHAT YOU DO IS NOT MATH’ turns that water O.F.F. PERMAnently. PERManently kids.

They dont have MODELS they can get certified any more, NONE of them who used the Mann/Briffa/Jones/etc methods do; not by serious statistical/instrumentation schools or foundations. That’s done because it is a simple matter to simply enter into federal regulations and state, that methods used must have endorsement by statistical/instrumentation professionals and teachers in a variety of fields.

Briffa.. with 12 trees.. HID it for YEARS. Wanted it submitted to sway policy.. but didn’t want to have to let people look under the hood, just like Mann didn’t.

Kevin “I’m the smartest man in the world” Trenberth with his LUDICROUS ‘earth energy budget’ who
when we gave him a satellite
found he couldn’t read the information from it: what he had thought and taught and testified was end-of-the-world runaway warming
was
situation – what? Oh yea situation normal.

Gavin Schmidt who whined about how ”the troposphere really is heating if you look for it”

Steven Schneider who tried to float the “the answer’s floating in the wind” paper which said – he had MODELED TEMPERATURE from WIND SPEED in the troposphere, and SURE ENOUGH

the troposphere is heating and yea.. it’s worse than we thought, and yea … all the radiosonde
satellite
aircraft
thermal sensors on earth
are broken. They don’t work.
And with the NEW MODEL thermal measurement was no longer needed because it was OBSOLETE compared to schneider’s model.

Can you believe those claims were allowed to be floated at large, by him and the people who hire him, trenberth etc

As science that was foretelling the END people, of the WORLD.

Which one of them has NOT had his fundamental methodology and acumen completely revoked in broad daylight….

But they’re a ring of government employees and Al Gore needed them to pulse his “i could have been president” rage tantrum.

Dispicable.

Many years ago, Gore and others would have been out on the front steps of the capital choosing pistols out of a matched set in a box, where someone called him out to see if he really stood by his beliefs, as he and his friends LAID WASTE to PEOPLE’S LIVES and CAREERS in the interest of sheer political will for their word

to be the law of the land.
