摘要: 插值是地球系统模式中为实现不同分量模式之间数据交换必不可少的一种数值手段。插值算法的研究不仅有利于分量模式自身的发展,更能有利地推进整个地球系统模式。针对地球系统模式中的插值,基于ESMF开发了一个通用的、灵活的、并行的插值算法研究平台THREP(Tsinghua Regridding Platform)。目前,THREP集成了ESMF-Regridding与THU-Remap插值库中的插值算法,用户能快速便捷地在THREP中接入与开发新的插值算法。THREP还提供了验证模块,便于进一步研究和对比插值结果。

Abstract: Regridding is a kind of numerical method for data transfer between different grids in coupled earth system models. The accuracy and performance of coupled earth system models can be improved by using proper regridding algorithms. THREP(Tsinghua Regridding Platform) is a versatile, flexible, parallel regridding research platform. It is implemented based on the ESMF infrastructure, integrates ESMF-Regridding and THU-Remap regridding algorithms library. THREP can also be used for developing new regridding algorithms and provide validation functionalities for further research.
