June GISS Temp up by 0.12°C

GISS LOTI went from 0.55°C in May to 0.67°C in June. Since TempLS rose by only a small amount, this is an unusually large discrepancy. Satellite lower troposphere temperatures also rose by even greater amounts.


Here is the GISS map for June 2013:



And here, with the same scale and color scheme, is the earlier TempLS map for June:

More data and plots

  1. for what it's worth, the big red blobs seem to be over parts of the globe that are relatively sparsely populated. Which suggests that thermopmeter measurements might be more than usually uncertain. But then again, the satellite results seem to suggest a very warm June. Any thoughts?

  2. Graeme,
    Actually, TempLS showed the least uptick this month. W Russia is a big red spot with plenty of obs, also SW USA. And there are plenty of stories of the Alaskan heat wave.

    On that point. it's useful to have the two plots. TempLS is a spherical ahrmonics plot, and so the red spots are produced by a wide area - on the other hand, sparsity can produce weird peaks. GISS is more grid oriented, so sparsity should produce blotches. If they agree, it's a good sign.

    Maybe the best way to see the validity of the warm bits is with a station plot. I'm planning to get that automatically updated.
