Linear trends were computed for two periods: 19582004 for the surface and radiosonde data and 1979-2002 for all three data sets. The analysis includes three compilations of surface data, two compilations of radiosonde data, and three analyses of MSU data.

However, if regional changes are large enough to have a measurable influence on global temperature, then these changes will be sampled and detected by the existing land-based networks. As such, why is this an issue when analyzing the differences among the data sets?

The authors say that "the variation m tropical lapse rate can be characterized as highly complex, with rapid swmgs over a few years, superimposed on persistent periods of a decade or more", but our guess is that much of this variation can be explained by changes m the mean temperature. Further, the authors say that the enhanced warming of the troposphere associated with surface warmmg gives "enhanced static stability" (lines 799 and 803)

11. The text m lines 299-301 makes it sound like the stratospheric cooling trend has been completely explained as a combination of the responses to stratospheric ozone depletion and cooling due to carbon dioxide.

13. In lines 320-323, the change to the Vaisala radiosonde m certain tropical areas is given as a possible reason for the differences m the two radiosonde data sets.

Are the free tropospheric temperatures more highly correlated with maximum surface temperatures than with minimum temperatures? If there is not a published reference on this, then should be removed.
