Over on Climate Audit, Jean S points out a curious anomaly in the March GISS Temperature data for Finland.
Maybe that’s where all of Trenberth’s “missing heat” went. Note the deep red anomaly is in a sea of blue that surrounds it.
Jean writes of the data:
GISS station values are even more spectacular, the warmest March on record is set in every Finnish station GISS is following. For instance, according to GISS, the mean March temperature in Sodankylä (61402836000) was a remarkable +1.5 °C beating the old record (-2.2 °C) from 1920 by 3.7 °C!
Well, according to the Finnish Meteorological Institute, March 2010 was colder than usual all over Finland, especially in the northern part. For instance, the mean temperature in Sodankylä was -10.3 °C, which is almost three degrees below the base period 1971-2000 average (-7.5 °C). So the GISS March value for Sodankylä is off by amazing 11.8 °C!
Even more curious, when you look at the NASA data from another division. NASA’s Earth Observations (NEO) The GISS Finlandic Temperature anomaly disappears!
Here are the satellite derived daytime and nighttime temperature anomalies for the world. Just like what the Finnish Meteorological Institute says, Finland was well below normal.
Here’s the daytime temperature anomaly:
Here’s the nighttime temperature anomaly:
The whole of Finland remains a cool blue in both images. So we have NASA NEO saying Finland is “below normal” and we have the Finnish Meteorological Institute saying below normal, but GISS shows a hotspot.
Gosh, who to believe?
I have a working theory as to why this happened, look for an update to this post if I’m able to confirm it – Anthony
UPDATE: GISS has posted a correction on their website which reads –
2010-04-15: The data shown between 4/13 and 4/15 were based on data downloaded on 4/12 and included some station reports from Finland in which the minus sign may have been dropped. NOAA updated GHCN on 4/13 by removing those data and we updated our displays today. The March 2010 global mean temperature was affected by about 2/100 of a degree Celsius, well below the margin of error (about 15/100 of a degree for monthly global means).
Back in January, I was working on a minus sign issue in data, and GISS making mention of this confirms it to be a real problem. I’ll have more later today. -A
UPDATE2: A commenter calls this “fraud” – folks please don’t go there. See below and wait for my next post. – A

even if Giss accidentally dropped the minus sign, -1.5 (C) would still be 8.8 degrees warmer than the -10.3 figure from the Finnish Meteorological Institute. there is only one word for this – fraud.
REPLY: Actually, it’s not fraud, but common human error. Give me a couple of hours and I’ll demonstrate how this happens. GISS is a consumer of GHCN data, compiled by NOAA, and while their quality control may be nonexistent or slipshod, it’s not fraud that they plotted this erroneously transmitted data. – Anthony

They hid the decline?
Reason? Two Words: James Hansen
Gotta love that satellite data!!
Do they have room under the carpet for this?
I think Giss have already found the problem and updated. discussing at Lucia’s
All the real Finnish data was missing so they had to look elsewhere using their now famous AlGORErithm. They thought those readings in Canada sure looked great and used them.
It also has NW Africa being warm when actually it wasn’t.
It’s just the latest of the Gisscapades.
Where do you get these images from? The NEO ones are far more convincing than the GISS.
It seems “global” warming is currently isolated to Canada. I’m sure that has nothing to do with the additional heat the Canadians are using near surface stations…??
I wonder what one of these images would look like during the MWP.
S see their latest comment is “2010-04-15: The data shown between 4/13 and 4/15 were based on data downloaded on 4/12 and included some station reports from Finland in which the minus sign may have been dropped.” ooops – how careless!!!
Absent quality data the meme is “fill ‘er in with red ink, boys”
Anthony,
I’ll be fascinated to see your theory. Somebody really needs to check those GISS algorithms for errors introduced when adjacent grid cell data is missing. Strongly contrasting anomalies between these data sources also show up in northern Canada, Peru, Algeria, Pakistan and South Africa — all areas with adjacent gray (empty) grid cells on the GISS map.

Gosh, who to believe?
I can believe GISTemp will be different from other data sets from around the world in that it will be warmer than the others.
GISS in not like a box a chocolates because you always know what you’re going to get.
I wish these guys would at least TRY to get on the same page. Sheesh.
Maybe it is an artifact of that 2008 September/October GISS data foible.

Remember that NASA that put men on the moon? This isn’t your daddy’s NASA.
i can`t find at giss data your figure one:
look at this if you try for your own:

REPLY: They have updated the data already.
Judith Curry, in comments at Pielke Fils and at Bishop Hill is saying that we need to have a whole new effort made to make a reliable temperature and paleo record. I think she’s had enough of the foolishness.
=====================
Umm…. baseline? GISS uses 1951 to 1980 the Finnish Met service 1971 to 2000. The baseline period for the Finnish met service is a considerably warmer period than the 1951 to 1980 period.
REPLY: They have updated the data already
really?
Can anyone tell me, whats going on over there?
Whats up with GISS? I can`t belive.
March 2010 : Russian announces that it may be COLDEST on re4cord.

The problem with this, I think, is that if there is one error like this, there could be many more. I find that worrying, and I simply use Roy Spencer’s data. At least this is way out in the public’s view.
Classic. Grounding of planes will cause global warming:

Hey? Is this game rigged? How come the Warmists always win? LOL.
Plus sign (+) … minus sign (-) … those minor little details will getcha every time.
just read the FT.com article about ongoing investigations into suspected hiring of Russian hackers by U.S. based climate skeptics. can’t wait until someone’s ass is nailed and would love it if it were you or Marc Morano in tribute to the disinformation you are so devoted to.
As soon as the missing heat notices that somebody has found it it disappears to hide somewhere else.

Perhaps the minus sign went missing in March too!
