LandscapeDNDC is partly based on the DNDC\r\nmodel and contains a series of new features \"with regard to process\r\ndescriptions, model structure and data I/O functionality.\" (Haas et al.,\r\n2012). LandscapeDNDC incorporates\r\nfunctions of DNDC, PnET-N-DNDC/Forest-DNDC and was further developed from the\r\nMoBiLE model framework (Rahn et al.,2012). \r\nLandscapeDNDC simulates carbon (C), nitrogen (N) and water related\r\nbiospehere-atmosphere-hydrospehere fluxes for forest, arable and grassland\r\necosystems. It incorporates different\r\nmanagement practises and vegetation types and allows dynamic simulation of\r\nlanduse change. Ecosystems are divided\r\ninto six substates: canopy air chemistry, microclimate, physiology, water\r\ncycle, vegetation structure and soil biogeochemistry (Haas et al., 2012). Modules, derived from physical and chemical\r\nprinciples, that describe soil environmental conditions, soil-chemistry\r\nintegrating microbial C and N turnover processes and vegetation dynamics are\r\nintegrated within the model (Rahn et al., 2012).
\r\nThe\r\nmodel can be applied at site scale and three-dimensional region\r\nsimulations. The integration of all grid cells synchronously forward in time\r\nfor regional simulations, enables efficient two-way exchange of states and easy\r\ncoupling to other spatially distributed models.
\r\nComparison of simulated and measured flux\r\ndata by Rahn et al. (2012) showed high agreement, however, freeze-thaw\r\nprocesses (potential strong impact of N2O emission) could not be reproduced as\r\nthe underlying processes are not included in the Landscape-DNDC.
