| Variable | Units | Description |
|---|---|---|
| cwd_fract | dimensionless | Ratio of CWD:(CWD + Soil Carbon) |
| resp_opt_water | dimensionless; range is between 0-1. | Optimal soil water for heterotrophic respiration as a fraction of the maximum possible soil water. |
| resp_water_below | dimensionless | Determines the rate at which heterotrophic respiration decays as soil water falls below resp_opt_water. |
| resp_water_above | dimensionless | Determines the rate at which heterotrophic respiration decays as soil water increases above resp_opt_water. |
| resp_temperature_increase | 1/K | Determines how rapidly heterotrophic respiration increases with increasing temperature. |
| N_immobil_supply_scale | 1/day | Supply coefficient for nitrogen immobilization. |
| r_fsc | Dimensionless; ranges between 0-1. | Fraction of the fast soil carbon pool going to heterotrophic respiration. |
| r_stsc | Dimensionless; ranges between 0-1. | Fraction of the structural soil carbon pool going to heterotrophic respiration (instead of to the slow pool). |
| r_ssc | Dimensionless; ranges between 0-1. | Fraction of the slow soil carbon pool going to heterotrophic respiration. |
| K1 | 1/day | structural soil carbon decomposition rate |
| K2 | 1/day | fast soil carbon decomposition rate |
| K3 | 1/day | slow soil carbon decomposition rate |
| N_decomp_lim | flag equal to 0 or 1. | Set to 1 if you want decomposition to be limited by nitrogen. |
