Roy W. Spencer, John R. Christy, and William D. Braswell – the team of pioneers of the satellite temperature measurements – have released
Version 6.0 [beta] of the UAH [AMSU] Temperature Dataset Released: New LT Trend = +0.11 C/decade [raw data]which is more compatible with the RSS AMSU dataset. In fact, UAH now shows a smaller (by 1/4 or so) warming trend than RSS. The trend has been exactly zero in the last 18 years. In the past, I tended to slightly prefer RSS AMSU – partly because I wanted to avoid suggestions that Spencer et al. aren't impartial just because they're skeptics (I surely do think that they are impartial). I also preferred a more silent method with which RSS was fixing their small bugs.
But this new release convinced me to play with the datasets again – do all kinds of Fourier analysis, Fourier filters, predictions, and so on. And I just found something that I want to share with you because it seems pretty exciting.
