Biome-BGC Carbon Workflow

A meteorology driven biogeochemical ecosystem model – Biome-BGC – simulates the carbon, water and nitrogen fluxes and pools of various terrestrial ecosystems. A new version of the model, called Biome-BGC MuSo has been developed to perform more realistic simulations in terms of soil hydrology, and improved ecosystem management options. The BBGC CARBON workflow executes a single simulation run at a given geographic location under that distinctive environmental circumstances, and for a specified time-span of years, past and/or future climate scenarios and management options.

A simulation requires specific inputs like:

  • local daily meteorology input dataset
  • a number of general ecophysiological constants as essential parameters
  • local site/soil parameters
  • annual atmospheric CO2 concentration (optional)
  • annual nitrogen deposition (optional)
  • annual mortality scenarios (optional only for MuSo)
  • annual groundwater scenarios (optional only for MuSo)
  • annual management scenarios (optional only for MuSo)
  • output control settings of Biome-BGC variables
  • spinup and normal initialization settings

Who is it for?

Scientists interested in carbon sequestration or carbon, nitrogen and water cycling simulations of various terrestrial ecosystems: i.e. grasslands, shrublands, forests, cultivated lands.

What is it for?

Studies of the impact of climate change or management scenarios on terrestrial ecosystems through models under different environmental conditions.

How does it work?

Preparation of the various inputs and settings is required first, then a simulation run can be performed. A run consists of a so-called spinup ("warming up") and pipelined normal ("productive") simulation phases. The Biome-BGC Project Database & Management System (BBGCDB) supports users to manage various Biome-BGC ecosystem modelling investigations embedded in Taverna workflow environment on the BioVeL Portal.

Expected results

Structured time-series (daily, monthly and/or annual) output text files, zipped and attached to the BBGCDB project record. BBGCDB project ID, URL and standard annual summary output result from the workflow.

Example of use: model comparison in the course of structural development

Comparing the Net Ecosystem Exchange (NEE), Leaf Area Index (LAI), Gross Primary Production (GPP) and Respiration (Reco) time-line of Biome-BGC MuSo 2.2 and Biome-BGC 4.1.1 MPI versions with the same parametrisation from 2006 to 2013 at Hegyhátsál, Hungary. Both models underestimate the variability of the carbon fluxes. The original model (4.1.1 MPI) performs better, because calibration was tuned to this version. Further improvements of version 2.2 was decided (remark: the recent version is MuSo 3.0). New calibration is needed for new model construction.
