Shared Socioeconomic Pathway (SSP) and Representative Concentration Pathway (RCP) combination for future scenarios The form is SSPn-m.m Where n is the SSP number and m.m is RCP radiative forcing at peak or 2100 in W/m^2 n is just the whole number of the specific SSP scenario. The lower numbers have higher mitigation - the higher numbers less mitigation, more than one SSP can result in the same RCP forcing hist means do NOT use a future scenario, just use historical data. Add a note to the output namelist about the options given to build-namelist CLM run type. 'default' use the default type of clm_start type for this configuration 'cold' is a run from arbitrary initial conditions 'arb_ic' is a run using initial conditions if provided, OR arbitrary initial conditions if no files can be found 'startup' is an initial run with initial conditions provided. 'continue' is a restart run. 'branch' is a restart run in which properties of the output history files may be changed. Horizontal resolutions Note: 0.1x0.1, 0.5x0.5, 5x5min, 10x10min, 3x3min and 0.33x0.33 are only used for CLM tools Land mask description Command line argument for setting up your simulation in a mode for faster throughput. By default turns off some options, and sets up for a lower level of output. When bgc_mode is some level of prognostic BGC (so NOT Satellite Phenology) it also sets up for accelerated decomposition. NOTE: THIS CORRESPONDS DIRECTLY TO THE env_run.xml VARIABLE OF THE SAME NAME. Set the env_run variable, rather than setting this directly. General configuration of model version and atmospheric forcing to tune the model to run under. This sets the model to run with constants that were set to run well under the configuration of model version and atmospheric forcing. To run well constants would need to be changed to run with a different type of atmospheric forcing. If TRUE, irrigation will be active (find surface datasets with active irrigation). If 1, turn on the MEGAN model for BVOC's (Biogenic Volitile Organic Compounds) Year to simulate and to provide datasets for (such as surface datasets, initial conditions, aerosol-deposition, Nitrogen deposition rates etc.) A sim_year of 1000 corresponds to data used for testing only, NOT corresponding to any real datasets. Most years are only used for clm_tools and there aren't CLM datasets that correspond to them. CLM datasets exist for years: 1000 (for testing), 1850, and 2000 Range of years to simulate transitory datasets for (such as dynamic: land-use datasets, aerosol-deposition, Nitrogen deposition rates etc.) Constant means simulation will be held at a constant year given in sim_year. A sim_year_range of 1000-1002 or 1000-1004 corresponds to data used for testing only, NOT corresponding to any real datasets. A sim_year_range that goes beyond 2005 corresponds to historical data until 2005 and then scenario data beyond that point. Namelist entries to demand be provided on the namelist. Description of the use case selected. Where dry deposition is calculated (from land, atmosphere, or from a table) List of chemical constituents that dry deposition will be calculated for File containing MEGAN emissions factors. Includes the list of MEGAN compounds that can be used in the Comp_Name variable on the file. MEGAN specifier. This is in the form of: Chem-compound = megan_compound(s) where megan_compound(s) can be the sum of megan compounds with a "+" between them. In each equation, the item to the left of the equal sign is a CAM chemistry compound, the items to the right are compounds known to the MEGAN model (single or combinations). For example, megan_specifier = 'ISOP = isoprene', 'C10H16 = pinene_a + carene_3 + thujene_a' MEGAN mapped isoprene emissions factors switch If TRUE then use mapped MEGAN emissions factors for isoprene.
