Biome-BGC MCE 1.4.1

Biome-BGC is a process-based biogeochemical model that can be used to simulate carbon, nitrogen and water fluxes of different terrestrial ecosystems. Two models were implemented: Biome-BGC 4.1.1 MPI (Trusilova et al. 2009) and Biome-BGC MuSo 3.0 (Hidy & Barcza 2014). Its has about 40 and 60 various parameters. The only way to estimate or set these parameters is "calibration" (data-model-harmonization or model-data-fusion), which demands a hugh amount of computational capacity. Monte Carlo Experiment (MCE) randomizes selected parameters of the model in a high number of replication, which provides pre-process results for further analysis, for example Sensitivity Analysis (SA), Generalized Likelihood Uncertainty Estimation (GLUE), etc.
The Biome-BGC MCE workflow starts a job on the ECOS server of MTA OK, which interacts with the EDGeS@Home Desktop Grid to distribute and execute the simulation task packages in many parallel instances.
Biome-BGC model simulations require several specific „parameter” datasets: spinup and normal initialization files (INI); daily meteorology dataset (METDATA); ecophysiological constants file (EPC); annual atmospheric CO2 concentration file (CO2 - optional); annual nitrogen deposition file (NDEP - optional); site parameters; output control of Biome-BGC variables; and Monte Carlo Experiment initialization file.
The Biome-BGC Projects Database & Management System was developed to easy prepare, manage and share all of the above mentioned datasets (files), investigations and provide interaction with Taverna workflows. Learn more about BBGCDB at http://ecos.okologia.mta.hu/bbgcdb/.

Scriptout1="The Biome-BGC Monte Carlo Experiment project (ID: "+prID+") has been created and submitted successfully. It runs off-line on the ECOS server of the Centre for Ecological Research of the Hungarian Academy of Sciences (MTA OK) and interacts with EDGeS@Home Desktop Grid, which can takes long time to run (i.e. several hours or days according to the number of MCE repetition requested). Please check the status and completeness of the MCE project regularly at the BBGCDB Project URL."; |
