They were prepared for the U.S. Climate Change Science Programs (CCSP) Synthesis and Assessment Report 1.1 entitled "Temperature Trends in the Lower Atmosphere: Steps for Understanding and Reconciling Differences" and available at www.climatescience.gov. That report gives more details about the individual surface, radiosonde, satellite Microwave Sounding Unit, and reanalysis datasets that were used in the report, including information on how to access them and sources of additional documentation. The only changes made to those original datasets were (1) creation of global and tropical (20S-20N) means from the original gridded or zonal-mean datasets, (2) normalization of all temperature anomalies to a consistent base period (1979-1999), and (3) creation of vertically-weighted layer-mean anomalies for additional layers not available in the original data products. The main purpose of these datasets was to facilitate the analysis presented in the CCSP report. They are being made available as part of the publication of that report. Each of the surface, radiosonde and MSU datasets has been used in previous peer- reviewed studies, has been quality controlled for gross errors, and has had adjustments in efforts to remove artificial time-varying biases. However, as discussed in much more detail in the CCSP report, it is likely that additional errors remain in these data. The reanalysis datasets are known to have uncorrected time-varying biases.

Each of the surface, radiosonde and MSU datasets is considered state-of-the- art global temperature data and has been used in previous peer-reviewed studies, has been quality controlled for gross errors, and has had adjustments in efforts to remove artificial time-varying biases. However, as discussed in much more detail in the CCSP report, because the original observations from which they were constructed were not designed for long-term climate monitoring, their long-term stability is not guaranteed and remaining time-varying biases may remain in some or all of the datasets. The reanalysis datasets are known to have time-varying biases and are therefore not reliable for trend analysis.
