Model And Data Assimilation Framework Development

C1的主要目标是基于全耦合陆地系统建模平台TerrSysMP生成流域规模的虚拟现实（VR），并与FOR 2131成员合作开发和分析数据同化框架（DAF）基于TerrSysMP的耦合与并行数据同化框架PDAF。这包括除了保持TerrSysMP隔间模块COSMO，CLM和ParFlow最新之外，还包括TerrSysMP的必要扩展，例如通过实施最新的CLM 4.5版本包含动态植被，以及利用适当的参数化改进河流和山坡流。该模型的开发需要在FOR 2131内部进行协调，以开发和实施合适的观测操作员，这些操作员能够处理VR和MVR模型的不同分辨率。由于TerrSysMP-PDAF的VR生成和执行的极端IT要求，C1还负责在Forschungszentrum Jülich JSC的高性能计算中心的基础设施JUQUEEN和JUROPA上实施这些系统，其中包括为高斯超级计算中心准备和执行计算时间提案。V.（GCS）与Geoverbund ABC/J的SimLab TerrSys合作。

The main objective of C1 is the generation of a catchment-scale Virtual Reality (VR) based on the fully-coupled terrestrial system modeling platform TerrSysMP, and the development and analysis of a Data Assimilation Framework (DAF) in cooperation with the members of FOR2131 based on the coupling of TerrSysMP with the Parallel Data Assimilation Framework PDAF. This includes besides keeping the TerrSysMP compartment modules COSMO, CLM, and ParFlow up to date also necessary extensions of TerrSysMP, such as the inclusion of dynamic vegetation via the implementation of the newest CLM version 4.5, and the improvement of river and hill slope flow utilizing appropriate parameterizations. The DAF development requires coordination within FOR2131 for the development and implementation of suitable observation operators, which are able to handle the different resolutions of the VR and the DAF model. Due to the extreme IT requirements for both the VR generation and execution of TerrSysMP-PDAF, C1 is also responsible for the implementation of these systems on the infrastructures JUQUEEN and JUROPA of the high-performance computing center at Forschungszentrum Jülich JSC, which includes the preparation and execution of compute time proposals for the Gauss Centre for Supercomputing e. V. (GCS) in cooperation with the SimLab TerrSys of Geoverbund ABC/J.
