Guest Post by Willis Eschenbach
Over at Roy Spencer’s excellent web site, Dr. Roy has a post up showing a sea surface temperature (SST) anomaly calculated from AMSR-E, TMI, and WindSat. Here’s his post of the results:
Figure 1. Global Microwave Sea Surface Temperature Update for Feb. 2013: -0.01 deg. C
Regarding these results, Dr. Roy says:
The anomalies are computed relative to only 2003-2006 because those years were relatively free of El Nino and La Nina activity, which if included would cause temperature anomaly artifacts in other years. Thus, these anomalies cannot be directly compared to, say, the Reynolds anomalies which extend back to the early 1980s.
So I figured I’d give him a hand by using the same 2003-2006 monthly anomaly baseline for the Reynolds Optimal Interpolation (OI) sea surface temperature, so we could have a longer dataset, and to see how his results compare to the Reynolds OI data.
I started by datapointing Dr. Roy’s data. I digitized it, and entered it into Excel.
Then I downloaded the Reynolds SST data (actual, not anomalies) from KNMI for the same area of the planet, 60°N to 60°S. Finally, I figured the monthly averages for the 2003-2006 period, and subtracted them from the Reynolds actual data to give the anomalies. Figure 2 shows the results:
Figure 2. Reynolds OI and Spencer Microwave SST measurements.
Not much to say, except that Dr. Roy’s results agree pretty well with the Reynolds OI data, and that there’s been no significant increase or decrease in SST in the last 15 years or so …
All data and calculations are here as an Excel spreadsheet.
My best regards to everyone,

Yes, and Willis Eschenbach:- quite right … it makes no practical difference regarding this question. Once again …

Dunno how reliable that would be. I overheard two corrections officers discussing on of their charges that had a tendency to strip off his clothes and leap onto the electric fencing. Ostensibly for the sheer entertainment value.
The story is real, whether they were being factual with each other is debatable.

Nice thought you wanting to remember me Willis but I real can’t fit your ego into my life.
All the best

I do love these tragic announcements about how someone is going to take their ball and go home, and it’s supposed to be this heavy thing, them depriving us of their priceless company and witty repartee. But they have to do it, you see … because I’m so unbearably bad.
Me?
James, you are the one who thought it was some kind of fun joke to “spoof” me. You are the one who thought it was great when KD poked the bear with a stick, and now that the bear bit your hand bit off as well, somehow you’re the noble guy and the problem is the bear’s ego is too big?
Really? That’s your excuse for your pathetic behavior, the bear’s ego?
And yet despite the fact that you can’t stand me, here you are, still barking at my ankles and disturbing respectable people, another man once again threatening to leave … but who hasn’t left quite gotten up the courage to leave yet, it’s dark outside, and besides, you gotta get in one more bark.
If you want to go, James, then why are you still here? Don’t stand on the order of your going. Don’t bother with final farewells, they just make you look operatic and ridiculous. Nobody cares if you leave, this is the internet. Someone equally unpleasant will show up soon, you won’t be missed.
Now, please be clear about my position in this, which is that you’re more than welcome to stay. If you want to go that’s your choice. If you stay and can get over your upset, you might learn something.
So the choice is yours, but if you go away, don’t go away mad, it’s hard on your liver … just go away. And if you stay … don’t stay mad either. Just remember your lesson about interfering when two men have a disagreement and a misunderstanding—if you want to take a hand in that kind of circus, the bear may bite it off …
Regards …
