These identifiers correspond to variables that can be read and/or set in the methane component.
Usage
CONCENTRATIONS_CH4()
PREINDUSTRIAL_CH4()
EMISSIONS_CH4()
NATURAL_CH4()
LIFETIME_SOIL()
LIFETIME_STRAT()Output variables
These variables can be read from the methane component.
- CONCENTRATIONS_CH4
Atmospheric methane concentration
- PREINDUSTRIAL_CH4
Preindustrial methane concentration
Input variables
These variables can be set in the methane component. The expected units string is given after each description.
- EMISSIONS_CH4
Methane emissions (
"Tg CH4")- PREINDUSTRIAL_CH4
Preindustrial methane concentration (
"ppbv CH4")- CH4_CONSTRAIN
N2O concentration constraint (
"ppbv CH4")- NATURAL_CH4
Natural methane emissions (
"Tg CH4")- LIFETIME_SOIL
Time scale for methane loss into soil (
"Years")- LIFETIME_STRAT
Time scale for methane loss into stratosphere (
"Years")
Note
Because these identifiers are provided as #define macros in the hector code,
these identifiers are provided in the R interface as functions. Therefore,
these objects must be called to use them; e.g., GETDATA()
instead of the more natural looking GETDATA.
