摘要: Abstract An update of the former version database and software for calculation CO2–air absorption coefficients taking line-mixing into account [Lamouroux et al. J Quant Spectrosc Radiat Transf 2010;111:2321] is described. In this new edition, data sets were constructed using parameters from 2012 HITRAN recent measurements line-shape parameters. Among other improvements, speed-dependent profiles can now be used if treated within first order approximation. This package tested laboratory spectra measured in 2.1 μm 4.3 μm spectral regions various pressures, temperatures CO2 concentration conditions. Despite improvements at room temperature, conclusions on quality are more ambiguous low temperature region. Further tests atmospheric thus required evaluation performances updated package.
