Generation of the Subsurface Climate Signal by Land Surface Processes in the North American Mid-Continent

该奖项旨在支持一项研究，该研究通过应用专门的陆地表面过程（LSP）模型，研究大气和固体地球之间的温度耦合，该模型先前开发用于描述卫星看到的向上传播的微波信号。项目成员将研究该LSP模型是否足以产生地热科学家用于气候重建的向下传播的温度信号，以及地表覆盖或平均降水变化对温度信号的影响。他们还将在一个特殊的环境下研究地下温度场的产生：北美中部大陆的大草原。研究人员将利用来自内布拉斯加州、南达科他州、北达科他州、马尼托巴省、萨斯喀彻温省和阿尔伯塔省的大量地下温度数据集来测试该模型的性能。

This award is to support a study that addresses the generation of the subsurface geothermal climate signature through the application of a specialized Land Surface Process (LSP) model, investigating the temperature coupling between the atmosphere and the solid earth with the LSP model previously developed to describe the upward-propagating microwave signal seen by satellites. Project members will investigate both the adequacy of this LSP model to generate the downward propagating temperature signal utilized by geothermal scientists for climate reconstructions, and the effects upon the temperature signal induced by changes in landcover or mean precipitation. They will also investigate the generation of the subsurface temperature field in a special setting: the prairie grasslands of the North American mid-continent. The investigators will test the model's performance with an abundant dataset of subsurface temperature profiles already available from Nebraska, South Dakota, North Dakota, Manitoba, Saskatchewan and Alberta.
