A simulation framework for terrestrial ecosystem models

LandscapeDNDC is a simulation framework designed for terrestrial ecosystem models on site and regional scales (Haas et al. 2013). It emerged from the MoBiLE model (Grote et al. 2009b), which consisted, among other components, of a DNDC version tailored for forest applications (Li et al. 2000; Stange et al. 2000) and the PSIM forest model (Grote et al. 2007). To create one comprehensive biogeochemical process description for both forested and agricultural ecosystems a DNDC version specifically designed for cropland simulations (Li et al. 1992a, b, 1994) was integrated. The modular design of LandscapeDNDC allows plugging in any choice of process descriptions for various parts of different natural ecosystems. One important feature of LandscapeDNDC is its capability to handle more than one site, i.e. simulating many cells (e.g. regions) with a single program invocation. In contrast to other models, in LandscapeDNDC all cells are synchronized with respect to time, which is highly significant for model coupling by means of a model-independent communication infrastructure (Haas et al. 2013; Klatt et al. 2017). Landscape is parallelized using MPI allowing the deployment on High Performance Computer (HPC) environments. LandscapeDNDC is written in C/C++ conforming to the standard known as C++ 11. It compiles and runs on:

• GNU/Linux (GCC, CLang, Intel, PGI, MinGW/GCC Cross-compiling for Microsoft Windows)
• MacOS X (GCC, CLang)
• Microsoft Windows platforms (MinGW/GCC, MSVC 8, MSVC 11)
