Comparison of Global Mean Temperature Series

Studies on the reconstruction of global mean temperature series are reviewed by introducing three series, HadCRUT3, NCDC, and GISS in details. Satellite data have been used since 1982 in NCDC and GISS series. NCDC series has the most complete spatial coverage among the three by using statistic interpolation technique. The weakened global warming in 2000–2009 as revealed in HadCRUT3 data is possibly caused by the lack of data coverage of this dataset over the Arctic. GISS and NCDC series showed much stronger warming trends during the last 10 years (~ 0.1 °C per 10 years). Three series yielded almost the same warming trend for 1910–2009 ( 0.70–0.75 °C per 100 years).CitationWen, X., G. Tang, S. Wang, et al., 2011: Comparison of global mean temperature series. Adv.
