Absolute humidity, mixing ratio
Absolute humidity?Absolute humidity is the water vapour content in the air (in gramme per cubic meter of air).
The mixing ratio of a volume of air is the rapport of the mass of water vapour content on the dry mass of air. It is expressed in g/kg.
Absolute humidity measurementMeasuring absolute humidity and mixing ratio can be done using a thermo-hygrometer.
