Biome-BGCMuSo v4.0.1 biogeochemical model Biome-BGCMuSo is a biogeochemical model that simulates the storage and flux of water, carbon, and nitrogen between the ecosystem and the atmosphere, and within the components of the terrestrial ecosystem. Biome-BGCMuSo was developed from the widely used Biome-BGC model that was created by the Numerical Terradynamic Simulation Group (NTSG), University of Montana. MS Windows executable of Biome-BGCMuSo v4.0 is available here: http://nimbus.elte.hu/bbgc/files/muso4.zip Sample input data is available at this link: http://nimbus.elte.hu/bbgc/files/HU-He2.zip Visit the official website of the model for additional information at http://nimbus.elte.hu/bbgc/ Documentation is available here at the GitHub repository or at the website of the model at http://nimbus.elte.hu/bbgc/documentation.html Note the possibility to use the model online without downloading the model code or executable: http://nimbus.elte.hu/bbgc/usingbbgc.html For instructions on compiling and running, see USAGE.txt Please contact us if you have any questions related to the model.
