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.
2008 1 -0.070
2008 2 -0.002
2008 3 0.079

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:
Year Jan Feb Mar
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.
