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 large size of these data bases, calculations are computationally too expensive to be used in regular CFD-simulations and are rather used for benchmark calculations to validate less complex models. In order to determine the accuracy of these simplified models, the accuracy of HITRAN/ HITEMP data bases must be known. We summarize important high temperature measurements and compare them with line-by-line calculations. Furthermore, we point out the difficulties that arise when the line-by-line method is used at high pressures.
