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). Web18 ott 2002 · In other spectral regions of low or medium opacity, however, differences between versions of the HITRAN database may be quantified. We present an analysis of three spectral ranges: the atmospheric window region between 750 and 1200 cm −1, and two regions of intermediate atmospheric absorption from 1200 to 1400 cm −1 and 1800 …
