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.
Here is a link to U.S. data for March: http://lwf.ncdc.noaa.gov/oa/climate/research/cag3/cag3.html
March was the 52nd coolest for the US, just south of middle of the road.
The map in the link I just posted looks a little different than the U.S. area of the GISS map.
if the chicoms had any brains they would report freezing temps to spike the GSMT downward, so that they can burn coal without being bothered.
More diabolical, they could report warmer temps so that everyone else would cut energy consumption and then they would win.

Both China and Russia hope to make a pile of dough selling mythical carbon credits to Europeans so they have an incentive to report warming when there is none.
@Evan Jones
They keep closing down stations in Russia and China within a radius of 1200 km, you kidder you. Within stations that have a March warming of +10° they removed this one from March evaluation, because it shows no warming trend at all:
gistemp station 205505270004.0.1 in Russia.
I was not referring to such outliers. I mean GISS NASA as a March outlier in general because of their Russian/Chinese early spring “surface heat wave”. Gotta wait for NOAA NCDC. I don’t know what you don’t like about NOAA?
Re: GISS/Satlleite differences
Check out March 1990 – very similar anomalies .
BTW Asia was very warm I mentioned this some weeks ago and that March was shaping up to be much warmer than Jan and Feb but was more or less dismissed.
The GISS tempertures for March are definitely well off on the high side in northern Europe. Compare the GISS set:
http://data.giss.nasa.gov/gistemp/
with the official Norwegian and Swedish Met Office Maps:

Note that to get comparable maps you have to change the GISS “base period” from the 1951-80 default to the the internationally used base period 1961-90 (and, yes, 1951-80 was appreciably colder than 1961-90).
Now, this is getting interesting. If you change the smoothing radius from 1200 to 250 km, the colder than normal temperatures in western and northern Scandinavia show up clearly, but with a 1200 km radius the temperatures there go up more than one degree. That smoothing algorithm must be a real work of art.
Another thing that shows up is the fact that GISS does not have a single station in central Scandinavia, which is quite ridiculous. There are any number of stations there, some of them (e g Trondheim and Östersund) with very long, good quality temperature series.
THE CENTRAL SUBJECT OF CLIMATOLOGY
In my opinion the researchers in climatology should put aside their work for a moment and focus their attention on the central and decisive subject of climatology. This is the extremely close correlation between the changes in the mean surface temperature and the small changes in the rotational velocity of the Earth in the past 150 years (see Fig. 2.2 of http://www.fao.org/DOCREP/005/Y2787E/y2787e03.htm), which has been ignored by the mainstream climatologists.
Since temperature cannot influence rotation to the observed degree and vice verca, a third agent must be driving the two. The solution is given in http://www.icecap.us/images/uploads/Lobert_on_CO2.pdf .
