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. ***

小行星9320136 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过去条件描述的有效性的唯一方法是主观的，通常是全球范围的概括性（例如。 该模型能再现赤道温度梯度吗？ 风会引起有机碳的上升流和沉积吗？） 除了一般情况外，没有办法将模型结果与地质矿床的出现情况进行比较。 我们相信，所提出的技术将允许定量比较模型结果与地质数据，显示模型是否准确地预测特定存款的形成条件。 这种定量比较将使建模者能够确定需要改变哪些输入参数才能更接近模拟古代气候。 该提案作为SGER提交，因为该技术如果得到开发，可以被许多建模人员用于评估将在不久的将来进行的古气候研究。 直到这项技术已经制定了古气候模型运行，代表了大量宝贵的超级计算机时间将不会产生数据，可用于定量验证。 SGER是合适的，因为迫切需要定义的技术之前，计划和拟议的GENESIS古气候模型运行启动。 ***
