Identifiers for quantities in the methane component

These identifiers correspond to variables that can be read and/or set in the methane component.

ATMOSPHERIC_CH4()

PREINDUSTRIAL_CH4()

EMISSIONS_CH4()

NATURAL_CH4()

LIFETIME_SOIL()

LIFETIME_STRAT()

Output variables

These variables can be read from the methane component.

ATMOSPHERIC_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")

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 function. Therefore, these objects must be called to use them; e.g., GETDATA() instead of the more natural looking GETDATA.
