1 sie 1972 · When carbon dioxide and water vapor are both present in a gas-mixture, the total emissivity is equal to the sum of emissivities of the two gases minus a correction term A~ due to overlap in some ~pectral regions = ~"2o + ~co2 - A~.

6 kwi 2011 · The mixture of gases in the atmosphere, water vapor, oxygen and carbon dioxide, has an emissivity/absorptivity of around 0.2, which means that the mixture of gases, as they are in the atmosphere, is about four times lower than the emissivity/absorptivity of the surface.
1 maj 2013 · High-precision measurements of CO2, CH4, N2O, CFC-12, CFC-11 (major greenhouse gases) and 10 minor halogenated gases from a globally distributed network of air sampling sites are used to...
1 lis 2018 · Gray gas emissivities of water vapor, carbon dioxide, and carbon monoxide are needed in many engineering calculations to determine radiative heat fluxes in high-temperature processes.
In the gas emittance subdirectory, tables emittance_CO2 and emittance_H2O correspond to the emissivities of carbon dioxide and water respectively in a mixture with non radiating gases.
Michael Alberti1 2, Roman Weber2, Marco Mancini2, Alexander Fateev3, Sønnik Clausen3 Abstract. Line-by-line (LbL) calculations using either HITRAN or HITEMP spectral data bases are often used for predicting gas radiation properties like absorption coefficients or emissivities. Due to the
7 lis 2008 · Using analytical methods, Felske and Tien (1973) reported total emissivity of luminous flames considering water vapor, carbon dioxide and soot. ... Later on, a new version of emissivity...
