Abstract:
The retrieved continuum absorption spectra in pure water vapor within near-IR bands 0.94 and 1.13 mm (10600 and 8800 cm–1) are investigated. The continuum was determined as a difference between the water vapor absorption spectra measured using a Fourier transform spectrometer and absorption spectra of the water monomers calculated using the HITRAN2016 database. The work is aimed at estimation of the maximum error in retrieval of the continuum absorption coefficient, which is caused by uncertainty in spectral line parameters in HITRAN2016. It is shown that the calculated errors exceed other types of errors within the absorption bands under studied.
