earthkit.meteo.thermo.fieldlist.specific_gas_constant(q)¶

Compute the specific gas constant of moist air.

Specific content of cloud particles and hydrometeors are neglected.

Parameters:: q (FieldList|Field) – Specific humidity (kg/kg)
Returns:: Specific gas constant of moist air (J kg-1 K-1). The result has the same type as the input q (FieldList or Field).
Return type:: FieldList|Field

The computation is based on the following formula:

\[R = R_{d} + (R_{v} - R_{d}) qss\]

where:

\(R_{d}\) is the gas constant for dry air (see earthkit.meteo.constants.Rd)

\(R_{v}\) is the gas constant for water vapour (see earthkit.meteo.constants.Rv)
