By Anthony Watts, Watts Up With That

Last week I posted the University of Alabama, Huntsville (UAH) Microwave Sounder Unit (MSU) global temperature anomaly data for February 2008 with a note that it showed only a marginal increase from January 2008 data, and remained near zero. The February 2008 global temperature anomaly data from RSS (Remote Sensing Systems of Santa Rosa, CA) is out, and is in good agreement with that. You can see it the raw RSS data yourself here.

First here is UAH satellite derived temperature anomaly. For February 2008, it shows a slight rebound from the -0.046C value of January 2008 to 0.016C for a slight change of .062C upwards.

Next we have the RSS satellite derived temperature anomaly. It also shows a slight rebound from the -0.080C value of January 2008 to 0.007C for a slight change of .0.073C upwards. The anomaly remains near zero as does the UAH data.

See some of the possible reasons why in Anthony’s post and also see a post with a note and graph from Dr. Richard Lindzen here.
