Chloroplastic CO2 concentration in Pa of class |
pars |
Concatenated parameters ( |
unitless |
Logical. Should |
use_legacy_version |
Logical. Should legacy model (<2.1.0) be used? See NEWS for further information. Default is FALSE. |

Symbol | R | Description | Units | Default |
| A | photosynthetic rate | mol CO2 / (m^2 s) | calculated |
| g_tc | total conductance to CO2 | mol CO2 / (m s Pa) | calculated |
| C_air | atmospheric CO2 concentration | Pa | 41 |
| C_chl | chloroplastic CO2 concentration | Pa | calculated |
| R_d | nonphotorespiratory CO2 release | mol CO2 / (m s) | 2 |

Value
Value in mol / (m^2 s) of class units
Examples
bake_par = make_bakepar()
constants = make_constants(use_tealeaves = FALSE)
enviro_par = make_enviropar(use_tealeaves = FALSE)

leaf_par = bake(leaf_par, enviro_par, bake_par, constants)
# Or bake with piping (need library(magrittr))
# leaf_par %<>% bake(enviro_par, bake_par, constants)
enviro_par$T_air = leaf_par$T_leaf
pars = c(leaf_par, enviro_par, constants)
