I calibrated my thermometer to the climate models but…?

… now it seems to be reading high in comparison with observations. Should I change back to using unadjusted measurements?

UAH data for Feb 2011 shows the global mean temp anomaly is negative. Both poles also negative. A summary is below, full data is at the link.

Feb 2011

Globe -0.01

NH -0.04

SH 0.01

NoPol -0.17

SoPol -0.18

USA48 -0.23

http://vortex.nsstc.uah.edu/data/msu/t2l%E2%80%A6

RSS data for Feb 2011 shows Global anomaly at +.051C, with both poles negative.

RSS data for Feb (regions are approximately equivalent to those in UAH summary above)

Globe 0.051

NH -0.012

SH 0.116

NoPol -0.11

SoPol -0.69

USA48 -0.563

Both of the above sources use the same baseline period : Jan 1979 - Dec 1998

Broken first link. My apologies. This one should work

Thank you 'A Modest Proposal' for pointing out the transcription error.

I've corrected this below, and with reference to your other comments, I have this time included the full column headings from the data. The number in the first column indicates the lattitude band to which the temperature anomaly applies.

RSS, Monthly Feb 2011

Latitude deg. Anomaly deg C

-70.0/82.5 0.051

-20.0/20.0 -0.222

20.0/82.5 0.054

-70.0/-20.0 0.361

60.0/82.5 -0.110

-70.0/-60.0 -0.580

Cont.USA -0.563

0.0/82.5 -0.012

-70.0/0.0 0.116

Full data at http://www.remss.com/data/msu/monthly_time_series/...

Neither RSS nor UAH reports or extrapolates data to the poles. RSS stops at 70S and 82.5N. UAH reports to 85S and 85N. The 'readme' that accompanies the UAH data (describing the latitude bands for the data) is here. http://vortex.nsstc.uah.edu/data/msu/docs/readme.m...

Pegminer... wow, you're touchy today. There was no rant i

was just having you on; and thank you for insulting my intelligence... I hope you feel better now. Have a nice day.

Edit AMP. Neither RSS nor UAH report to the poles. The UAH column heading "NoPol" refers to 60N to 85N, "SoPol" refers to 60S to 85S.

    Their answer? You're questioning our data and methods. You must be a denier in the pocket of the oil companies.

    Not sure why you would calibrate your thermometer to a GCM. Calibration is usually done with actual measurements, not calculated output.

    Where are you getting your figures from? Yes, you gave links, but not all of those numbers appear in the spreadsheets. For RSS, they give no figures at all north of 82.5 or south of -70, and the "-0.69" number is not in any of the February numbers. The "-0.11" figure is also mis-attributed: the actual location is not the North Pole, but 60-82.5˚N.

    UAH also extrapolates to the poles, it does not have any data for them. The figures ought to be taken with a grain of salt, as, if I'm not mistaken, their site gives no in-depth explanation of the procedure behind this.

    Kind of ironic considering the crap that GISS gets.

    Also, those are NOT unadjusted data.

    (And a quick comment too, since this was a fairly recent change in UAH: their base period is now a full 30 year period, from 1981 to 2010. Spencer discusses the change at his blog below.)

    Edit: RSS doesn't report polar values. UAH does, and you cited them. Again though, the satellite doesn't actually orbit that far toward the poles, just short under 10˚.

    But thanks for the update.

    Could you at least TRY to at least ask a question and not just rant? You didn't calibrate anything and I doubt you have the foggiest idea why anyone would adjust temperatures in the first place. You could have asked a real question that would have been more effective as rhetoric and a lot less of a rant.

    I think you should just combine the two polinue charges and you shoul be ready to go.

    Put the climate model in the garbage can, garbage in garbage out. When you have a group determined to prove their beliefs, it's like a religion, and religion and logic just don't Jive.
