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.

摘要 ATM-9320004波拉克，亨利N。 全球钻孔温度和气候重建数据库（Global Database of Borehole Temperatures and Climate Reconstructions） 该研究奖致力于设计，组装，分析和解释过去1000年与气候变化有关的大陆地热观测的全球数据库。 这一时间间隔跨越工业化前和工业化时期，并与评估自然变率和人类活动对地球表面温度的影响有关，时间尺度为世纪至千年。 该数据库将包括：（1）实地调查的基本地热观测，包括钻孔温度与深度数据、热物理性质和地点说明;（2）通过对基本实地观测进行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/或对各个地点进行加权平均得出的区域化综合历史;及（4）与本地气象及其他邻近代用资料的互相参照。 该数据库将包括分布在六大洲的几百个地点的数据。
