Did you know that RATPAC is more accurate than Spencer and Christie?

Table 1: Lower (TLT) and mid-troposphere temperature (TMT) estimates from various groups

Group	TMT Trend (°C/decade)	TLT Trend (°C/decade)
UAH	0.05	0.14
RSS	0.09	0.14
Fu et al.	0.13	--
V & G	--	0.20
Zou et al.	0.13	--
RATPAC	--	0.18

Note that the RATPAC radiosonde (weather balloon) data are in close agreement with the higher tropospheric temperature estimates, as are the HadAT2 radiosonde data (Figure 3).

Figure 3: HadAT2 radiosonde data (black) vs. UAH (blue) and RSS (red) lower troposphere temperatures, and HadCRUT3 surface temperatures (green)

This provides yet another reason why it is unwise to assume that UAH is correct and the models/physics or surface temperature data are wrong. It is the UAH data that is the outlier.
