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.

C1的主要目标是基于全耦合地面系统建模平台TerrSysMP生成流域尺度的虚拟现实（VR），并与FOR2131成员合作，基于TerrSysMP与并行数据同化框架PDAF的耦合开发和分析数据同化框架（DAF）。这包括除了保持TerrSysMP单元模块COSMO， CLM和ParFlow的更新之外，还包括TerrSysMP的必要扩展，例如通过实现最新的CLM 4.5版本包含动态植被，以及利用适当的参数化改善河流和山坡流量。DAF的开发需要在FOR2131中进行协调，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DAF模型的不同分辨率。由于TerrSysMP-PDAF的VR生成和执行对IT的极端要求，C1还负责在Forschungszentrum j<s:1> lich JSC高性能计算中心的JUQUEEN和JUROPA基础设施上实施这些系统，其中包括与Geoverbund ABC/J的SimLab TerrSys合作，为高斯超级计算中心（GCS）准备和执行计算时间建议。
