WebINIS Repository Search provides online access to one of the world's largest collections on the peaceful uses of nuclear science and technology. The International Nuclear Information System is operated by the IAEA in collaboration with over 150 members. WebTL;DR: HITRAN offers a Python API called Hapi which gives the possibility to fetch spectral data from the database directly, and convert it into absorbance spectra within tens of line of code. It is useful and quite user-friendly.
Web13 nov 2012 · The influence of the updates to the HITRAN database on the off-line to on-line ratio calculation in the narrow spectral region 4855–4880 cm−1 could be equivalent to a change in CO2 of more than 50 ppmv. Use of the HITRAN 2004 database will lead to an underestimate of the column CO2 abundance in the 2.06- and 1.61-µm spectral ... Web25 ott 2024 · The detector signals were acquired by a 18-bit ADC. Sixty-four spectra were averaged, followed by a 3-fold moving average. As frequently used with DAS, gas concentrations were obtained by fitting the measured spectra with available line parameters from the HITRAN spectral database (Rothman and Gordon, 2013).
