Approximate Radiation Properties of Air between 2000 and 8000 Degrees K.

Forrest R. Gilmore

ResearchPublished 1964

The spectral absorption coefficient for equilibrium air at five temperatures between 2000 and 8000 deg K and six densities between 10 and 0.00001 times the standard density has been calculated by correcting the 1959 tables of Meyerott, Sokolov, and Nicholls for revised values of the f-numbers of the molecular band systems, and adding the contributions of several band systems and continua not included by those investigators. Band systems of nitrogen dioxide make an important contribution to the absorption coefficient of air below 6000 deg K. The uncertainty in this contribution is probably the biggest source of uncertainty in the air results. Tables of the spectral absorption coefficient, the Planck mean absorption coefficient, the spectral emission coefficient, the total emission rate, and the visible emission rate are included.
