GRGC (SGER) Relating Climate Model Data to Geologic Deposits

9320136干草该提案将开发一种技术，在气候模型数据和地质观测之间提供定量联系。到目前为止，评估古气候模型数据作为对过去条件的描述的有效性的唯一手段一直是主观的，通常是全球范围的概括(例如。该模型是否再现了经向温度梯度？风是否会导致有机碳的上涌和沉积？)除了从一般意义上讲，无法将模型结果与地质矿床的产状进行比较。我们相信，所提出的技术将允许将模型结果与地质数据进行定量比较，以显示模型是否准确地预测了特定矿床的形成条件。这种定量比较将使建模人员能够确定需要更改哪些输入参数才能更接近模拟古代气候。该提案被作为SGER提交，因为如果开发出这项技术，许多建模人员可以使用该技术来评估即将在不久的将来进行的古气候研究。在这项技术完成之前，古气候模型的运行，代表了大量宝贵的超级计算机时间，不会产生可用于定量验证的数据。SGER是适当的，因为在启动计划和拟议的Genesis古气候模型运行之前，迫切需要定义该技术。***

9320136 Hay The proposal will develop a technique that provides a quantitative link between climate model data and geological observations. Until now the only means of assessing the validity of paleoclimate model data as a description of past conditions has been in terms of subjective, often global scale generalities (eg. Does the model reproduce the meridional temperature gradient?; Would the winds cause upwelling and deposition of organic carbon?). There has been no way to compare the model results with the occurrence of geological deposits except in general terms. We believe that the technique proposed will allow quantitative comparison of model results with geologic data, showing whether or not the model accurately predicts conditions of formation of a specific deposit. This quantitative comparison will enable modelers to determine what input parameters need to be changed to come closer to simulating the ancient climate. The proposal was submitted as an SGER because the technique, if developed, could be used by a number of modelers to evaluate paleoclimate studies to be run in the near future. Until the technique has been worked out the paleoclimate model runs, representing a large amount of valuable supercomputer time will not result in data that can be used for quantitative validation. SGER is appropriate because of the urgent need to define the technique before planned and proposed GENESIS paleoclimate model runs are initiated. ***
