Changes

The ISPM also states: "Adjusting T2 data to remove an estimated contribution from the stratosphere yields tropospheric trend coefficients ranging from about 0.12 oC to 0.19 oC per decade, '''depending on the method.'''" [ISPM 2.1c] In fact, But the method employed makes little difference. The difference between UAH and RSS results is almost entirely appears to be mainly due to the different T2 differing tropospheric data filtering and adjustments calibrations '''priorindependent''' to of adjustments to remove spurious stratospheric cooling, as seen in ; a comparison of the "Troposphere" T2 and TMT (RSS stratospheric removal methodmid-troposphere) trends also show similar differences in trends between the UAH and "Lower troposphere" (UAH removal method) panelsRSS. [AR4 Fig. 3.18] For example, RSS adjusted trend is 0.19 if the RSS method is employed, and 0.18 if the UAH method is employed.
