Variables

Variable 12 – Emissivity of water vapor

Emissivity εH2O of water vapor at a total pressure of 1 bar as a function of temperature and the product pH2Oseq.

Variable 19 – Correction factor for water vapor

Correction factor f for water vapor (total pressure p ≤ 1 bar). For pressures p > 1 bar you must use Eq. (19)

Variable 24 – Emissivity of carbon dioxide

Emissivity εCO2 of carbon dioxide at a total pressure of 1 bar as a function of temperature and the product pCO2seq.


Variable 24 – Emissivity of any gas

Emissivity of ammonia

Emissivity of ammonia at a total pressure of 1 bar as a function of temperature and the product pNH3seq.


Emissivity of methane

Emissivity of methane at a total pressure of 1 bar as a function of temperature and the product pCH4seq.


Variable 32 – Correction of emissivity

Correction Δε for mixtures of carbon dioxide and water vapor at (a) 130°C, (b) 540°C, and (c) 920°C and above

Variable 36 – Emissivity of sulfur dioxide

Emissivity εSO2 of sulfur dioxide at a total pressure of 1 bar as a function of temperature and the product pSO2seq.
