9809706 MastersSince the publication of the Preliminary Reference Earth Model (PREM) in 1981, there has been a dramatic increase in the quantity and quality of seismic data as well as an appreciation and understanding of the effects of 3D structure. Furthermore, there is now a sense that a model unifying several aspects of global geophysics and geochemistry is a possibility in the forseeable future. Such thinking has led to several CSEDI-sponsored workshops on new Earth models, the latest being at La Jolla in May, 1997. There is now general agreement that a reference Earth model should be broadly interpreted as a suite of models, data sets, and codes. As a consequence, this grant broadens the scope of the P.I's. collaborative work on reference Earth models. The overall objective is to provide the community with a variety of internally compatible data sets and some of the codes needed to model them. They expect that providing these "reference data sets" will result in more tightly constrained 3-dimensional models, and might naturally lead to a provisional 3-D reference Earth model.

9809706大师自1981年初步参考地球模型（PREM）出版以来，地震数据的数量和质量以及对3D结构影响的认识和理解都有了显着提高。 此外，现在有一种感觉，在可预见的未来，一个统一全球地球物理学和地球化学若干方面的模型是可能的。 这种想法导致了CSEDI赞助的几次关于新地球模型的研讨会，最近的一次是1997年5月在拉霍亚举行的。 现在人们普遍认为，参考地球模型应该被广义地解释为一套模型、数据集和代码。 因此，这笔赠款扩大了私人侦探的范围。地球参考模型的协作工作。 总体目标是为社区提供各种内部兼容的数据集和一些建模所需的代码。 他们希望提供这些“参考数据集”将导致更严格的约束三维模型，并可能自然导致临时的三维参考地球模型。
