Abstract
An example of high-resolution (0.08 cm−1), absolute transmission spectra of a 5-km atmospheric path is presented. Precise transmission and wavenumber calibration of the spectra were obtained from infrared laser extinction measurements. A comparison of these spectra to line-by-line calculations shows excellent agreement in the spectral region between 2480 and 2800 cm−1 (3.57 to 4.03 μm).
