Global Database of Borehole Temperatures and Climate Reconstructions

Pollack, Henry N. Michigan大学题目：钻孔温度和气候重建全球数据库本研究奖旨在设计、组装、分析和解释一个与过去1000年气候变化相关的大陆地热观测全球数据库。这一时间间隔跨越了前工业化时期和工业化时期，与在世纪至千年时间尺度上评估地球表面温度的自然变率和人为强迫有关。该数据库将包括：(1)现场调查的基本地热观测数据，包括钻孔温度与深度数据、热物理性质和地点描述；(2)通过基于基本现场观测的标准化反演程序得出的每个地点的地表温度历史；(3)通过联合反演和/或单个地点的加权平均得出的区化复合历史。(4)交叉参考当地气象和其他附近代理数据。该数据库将包括分布在六大洲的数百个地点的数据。

Abstract ATM-9320004 Pollack, Henry N. University of Michigan Title: Global Database of Borehole Temperatures and Climate Reconstructions This research award addresses the design, assembly, analysis and interpretation of a global data base of geothermal observations on continents relevant to climate change over the past 1000 years. This time interval spans both the pre-industrial and industrial periods, and is relevant to an assessment of both natural variability and anthropogenic forcing the Earth's surface temperature at the century to millennial time scale. The database will comprise (1) basic geothermal observations from field surveys, including borehole temperature vs. depth data, thermophysical properties and site descriptions, (2) a ground surface temperature history derived for each site by a standardized inversion procedure operating on the basic field observations, (3) regionalized composite histories derived by joint inversions and/or weighted averaging of individual sites, and (4) cross references to local meteorological and other nearby proxy data. The database will include data from several hundred sites distributed over six continents.
