Four of the proxy series are from the Tibetan Plateau: the Guliya and Dunde ice cores, Dulan tree-ring record, and a southern Tibetan Plateau composite tree-ring record. Five series were obtained from Eastern China and Japan, including Jinchuan peat, eastern China documentary evidence, tree-ring series from Japan, and two Taiwanese lake sediment records. Three temperature reconstruction time series are presented. The first, called "H-res", was derived by averaging only the high-resolution proxy records. Considering the relatively large age uncertainties of the lake-sediment and peat records (±50 years), these records were not included in this composite. The second composite, named "Complete", was derived directly by averaging all 9 proxy records. The "Weighted" composite reconstruction was formed by combining area weighted regional proxy records. Wang and Gong [2000] used this method to establish an annual mean temperature series of China for the period 1880 to 1998. They divided the Chinese territory into ten regions according to inter-correlations among gridded 1° × 1° latitude × longitude mean temperature records. According to Wang and Gong [2000], the area weights of Eastern China, Dunde ice core, Guliya ice core, southern TP tree-rings and Jinchuan peat are 0.329, 0.198, 0.149, 0.182 and 0.131, respectively. The data of Great Ghost Lake and Jiaming Lake in Taiwan were considered with an area weight of 0.011. ABSTRACT SUPPLIED BY ORIGINATOR: Three alternate China-wide temperature composites covering the last 2000 years were established by combining multiple paleoclimate proxy records obtained from ice cores, tree rings, lake sediments and historical documents. Five periods of temperature variation can be identified: a warm stage in AD 0–240, a cold interval between AD 240 and 800, a return to warm conditions from AD 800–1400, including the Medieval Warm Period between AD 800–1100, the cool Little Ice Age period between 1400–1920, and the present warm stage since 1920. Regional temperature variation is found during AD 800–1100, when warm conditions occurred in Eastern China and in the northeastern Tibetan Plateau and in AD 1150–1380, when the southern Tibetan Plateau experienced a warm interval. In contrast, evidence for cool conditions during the LIA is more consistent among the proxy records. The temperature reconstructions for China and the Northern Hemisphere show good agreement over the past millennium.
