The MEMC model configuration for COMISSION
COMISSION_config.RdThe COMISSION configuration is based off of Ahrens et al. 2015. The model uses MM for the DOM uptake, RMM for POM decomposition, and LM for MB decay; see dynamics for more details.
Format
An object created from memc_configure, containing the following elements.
- name
COMISSION
- table
table of the dynamics used by this model configuration; see dynamics for more details.
- params
data table of the model parameters; see memc_params for more details.
- state
vector of the initial state values; see memc_initial_state for more details.
