bytran is an application for calculating atmospheric and molecular absorption spectra using the HITRAN database and the line-by-line method. The concentrations of molecules, pathlength, atmospheric pressure, temperature, and other input parameters are used to model the gas mixture optical transmission spectra as a function of wavelength.
Additional information is available at the bytran website and in the following publication, http://dx.doi.org/10.1007/s12145-017-0288-4 (a view only version of this publication is available at http://rdcu.be/piDB).
1) Fixed a mistake in the bytran algorithm in that the Loschmidt's number was specified at a standard temperature of 273.15K instead of at 296K (an ~ 8% difference).
2) Fixed a programming error preventing the usage of the external storage causing bytran to terminate after the HITRAN database downloads and on program quit.
