A few days ago I posted the results of the RSS Microwave Sounder Unit (MSU) global temperature anomaly data by RSS (Remote Sensing Systems of Santa Rosa, CA).
For March 2008 it has moved a little higher, with a value of .079°C for a change (∆T) of 0.081°C globally from February.

University of Alabama, Hunstville (UAH) published their data set on April 8th, and it is in good agreement with the RSS data. The ∆T for March was .074 degree C

GISS also published their global temperature anomaly data, which you can see here, and it is significantly different than two global satellite data sets:

2008 .12 .26 .67
I haven’t bothered to plot the graph yet, but the ∆T of .41 degree C change upward from February 2008 is quite large, and according to one of our commenters, JM:
The GISS Feb to Mar temperature change is the largest one month change in the entire record based on my macro search.
I have not verified that, but it seems plausible. We’ll see if GISS remains the outlier data set when HadCRUT publishes soon, I expect before the end of the week.
What better place to measure sea level than Colorado? 😉

“We should just keep it simple, and let it evolve with time…just list each component individually at the end of each month., and say something like 5 out of seven indicators point to cooling, with ocean temperature (the big one) showing a drop.
You hit the nail on the head. If our bureaucrats can’t understand or comprehend the little they’re supposed to do by law, how on earth can they understand a myriad of numbers. Perhaps two different sets of numbers would be even better: one for individuals seeking a more in depth view and the other for the Pogies and elected officials!

I hope this isn’t off topic but I really am wondering about this. If sea level is rising and ice is at very high levels, where is the extra H2O coming from?
Normally i would say thermal expansion. But as the ocean temps do not seem to be cooperating . . .
Perhaps there is thermal expansion warming ‘way. ‘way deep due to undersea volcanoes or something. Perhaps there is some uplift in the sea floor. And most areas are either sinking or uplifting. The old sea-witch “Axe” Moerner claims the IPCC carefully cherry picked its SL data from sinking areas (and dumpered his peer review on the matter) and SL actually has not been rising much at all.
Also an albedo measurement will be a great indicator
Another vote for that, then. (Yoo-hoo!)

Hey Mike, that’s a great question and one everyone seems to be wrestling with right now. This is especially stange in that SST have been dropping and the waters should be contracting slightly.

Is there a global inventory of water?
Oceans
Lakes
Rivers
Ice
Total
Just wondering
Sorry forgot atmospheric…
Sea level has been basically flat the last couple of years. (Three IIRC) Google-fu is failing me at the moment though.
John Cook,
Maybe the Argo data hasn’t been adjusted and homogenized yet.
Mike, what extra water?
Here at GISS’s site you can see why they are so much warmer.
http://data.giss.nasa.gov/gistemp/
Click on Global Maps, and make the Mar 08 map with or without SST’s.
Almost the entire Asian continent fried in March. RSS does show it being much warmer in the same area, but GISS really seems to over do it.
Mike, the ice that is at high levels is sea ice. Since it is floating in the ocean, it doesn’t influence sea levels. Only increasing ice on land in net terms will do that.
To remove the offset differences between the series, take a look at the first derivative:
http://www.woodfortrees.org/plot/uah/from:2007/derivative/plot/rss/from:2007/derivative/plot/hadcrut3vgl/from:2007/derivative/plot/gistemp/from:2007/derivative
This shows GISTEMP has been more variable *in both directions* recently, but there is something unusual about the last point, clearly.
Basil: I was just about to add an “every” process which will allow selection of (usually) every 12 samples – then you can compare the same month year-to-year.

Thanks for the link – exactly what I was looking for.
Looking at the sea level data, it seems a sharp sea level rise occurred in 1997 just before the super 1998 El Nino. I’d say this was maybe due to thermal expansion. If this is not the case, could someone tell why this happened so?
Crosspatch and Mattn, the amount of ice in Greenland and in the Antarctic dwarves all other ice on earth. This is the ice that some people worry about because it isn’t floating. Since this ice is at very high historic levels, and sea level is apparently also rising, it seems that we must have extra water. There’s probably a simple explanation for this.
Actually the graph at http://sealevel.colorado.edu/ seems to have leveled off a little recently. I guess as the earth cools we should expect some lowering of sea level.
Russian and Chinese surface stations 4 – 8 degrees above normal in GISS-Network in March 2008?? I doubt that!
Question: Is there a climate audit going on for the Russian and Chinese datasets of surface stations? This seems to be the great +++ outliers compared to satelite measurements. Gotta track that problem down.
This shows GISTEMP has been more variable *in both directions* recently,
Yes; the distinct mark of the heat sink. Exaggeration of temperature increase during warming. Exaggerated regression during cooling.
You see, there’s a part of this site everyone seems to be forgetting about: “How not to measure temperature.” Remember? (nudge-nudge)
This seems to be the great +++ outliers
Nonsense, old son. We are promised that all outliers are removed from data. Promised! Why, it’s Step One of the NOAA adjustment procedure (really). What you require is a greater trust in our great institutions.
I find your lack of faith . . . disturbing.
My theory is jeez is an alias of IowaHawk.
How’s about a little soliloquy by Lear’s fool?
Poor Tom’s a-cold!
Mike, I know what you’re talking about. I was being sarcastic (I’m kinda that way).
I clicked the GISS map link supplied by climatepatrol, and the area on the map that is more than 4 above normal over Asia is incredibly HUGE! It’s hard to believe. I look at hemispheric 500mb weather maps frequently, and I sure don’t remember seeing such a vast area of anoumalously high 500mb heights on that side of the world last month. Maybe I missed it(?).
