What’s Up With UAH ?

For a few days last week, I was afraid that the University of Alabama in Huntsville had had their computers hacked, as Channel 5 of their satellite record showed just a single data point.

By the 16th June 2010, however, full data for the year to date was visible again, but it seemed that data from previous years was not available, as the chart legend said that the temperature at 14,000 feet above the Earth’s surface was 457.01 degrees Fahrenheit higher than last year (as you can see in the snapshot above). I concluded, quite logically I feel, that something was amiss.

What’s up with UAH, I asked myself ?

And why does the curve look different than previously ?

Here’s the snapshot from 26th May 2010 :-

Anyway, all is now relatively clearer : the data is probably being re-input, perhaps massaged or less-smoothed :-

Still rather warmer than last year, though, isn’t it ?
