TECO-CNP is a coupled carbon–nitrogen–phosphorus terrestrial ecosystem model with an integrated data assimilation algorithm. The model is currently available for site‑level simulations and is designed to advance research on the impacts of global change on terrestrial ecosystems through a model–data fusion approach.
The TECO-CNP model has evolved from its precursor, Terrestrial Ecosystem Model (TECO). Developed to simulate carbon dynamics in terrestrial ecosystems, TECO served as the foundation for process‑based biogeochemical modeling within the TECO model family. TECO‑CNP expands upon this by explicitly incorporating nitrogen and phosphorus cycles, embedding a data assimilation capability. This capacity allows for more efficient parameter optimization, facilitating the model’s application across multiple sites and ecosystem types. For a detailed description of TECO-CNP, please refer to the model description paper.
The TECO-CNP model requires eight essential meteorological forcing variables to drive ecosystem simulations. These include air temperature, soil temperature, relative humidity, vapor pressure deficit, precipitation, wind speed, photosynthetically active radiation, and atmospheric carbon dioxide concentration. Detailed specifications for data formatting can be found in the documentation.
